An assignment statement sets and/or re-sets the value stored in the storage location(s) denoted by a variable name; in other words, it copies a value into the variable. [1]

The assignment operator allows us to change the value of a modifiable data object (for beginning programmers this typically means a variable). It is associated with the concept of moving a value into the storage location (again usually a variable). Within most programming languages the symbol used for assignment is the equal symbol. But bite your tongue, when you see the = symbol you need to start thinking: assignment. The assignment operator has two operands. The one to the left of the operator is usually an identifier name for a variable. The one to the right of the operator is a value.

Simple Assignment

The value 21 is moved to the memory location for the variable named: age. Another way to say it: age is assigned the value 21.

Assignment with an Expression

The item to the right of the assignment operator is an expression. The expression will be evaluated and the answer is 14. The value 14 would be assigned to the variable named: total_cousins.

Assignment with Identifier Names in the Expression

The expression to the right of the assignment operator contains some identifier names. The program would fetch the values stored in those variables; add them together and get a value of 44; then assign the 44 to the total_students variable.

Difference between declaration statement and assignment statement in C? [duplicate]

I am new to programming and trying to learn C. I am reading a book where I read about these statements but could not understand their meaning.

2 Answers 2

Declaration:

Assignment:

Declaration and assignment in one statement:

Declaration says, "I'm going to use a variable named " a " to store an integer value." Assignment says, "Put the value 3 into the variable a ."

(As @delnan points out, my last example is technically initialization , since you're specifying what value the variable starts with, rather than changing the value. Initialization has special syntax that also supports specifying the contents of a struct or array.)

• 6 The third isn't an assignment. It's initalization. –  user395760 Commented Apr 22, 2014 at 18:33
• 6 It matters in C insofar you can do things in initialization that you can't do in assignment. For example int a[2] = {}; works but int a[2]; a = {}; doesn't. –  user395760 Commented Apr 22, 2014 at 18:41

Declaring a variable sets it up to be used at a later point in the code. You can create variables to hold numbers, characters, strings (an array of characters), etc.

You can declare a variable without giving it a value. But, until a variable has a value, it's not very useful.

You declare a variable like so: char myChar; NOTE: This variable is not initialized.

Once a variable is declared, you can assign a value to it, like: myChar = 'a'; NOTE: Assigning a value to myChar initializes the variable.

To make things easier, if you know what a variable should be when you declare it, you can simply declare it and assign it a value in one statement: char myChar = 'a'; NOTE: This declares and initializes the variable.

So, once your myChar variable has been given a value, you can then use it in your code elsewhere. Example:

This prints the value of myChar and myOtherChar to stdout (the console), and looks like:

If you had declared char myChar; without assigning it a value, and then attempted to print myChar to stdout, you would receive an error telling you that myChar has not been initialized.

• You mostly describe the difference between declaring a variable and not initializing it vs. declaring a variable and initializing it. –  user395760 Commented Apr 22, 2014 at 18:42

Assignment (computer science)

Certain use patterns are very common, and thus often have special syntax to support them. These are primarily syntactic sugar to reduce redundancy in the source code, but also assists readers of the code in understanding the programmer’s intent, and provides the compiler with a clue to possible optimization.

Today, probably the most generally used notation with this operation is x = expr (initially Superplan 1949–51, popularized by Fortran 1957 and C). The 2nd most generally used notation is(1) x := expr (initially ALGOL 1958, popularised by Pascal). A number of other notations will also be being used. In certain languages, the symbol used is considered being an operator (and therefore a job statement in general returns something). Other languages define assignment like a statement (and therefore it can’t be utilized within an expression).

In computer programming, an assignment statement sets or re-sets the value stored in the storage location(s) denoted by a variable name. In most imperative computer programming languages, assignment statements are one of the basic statements. Common notations for the assignment operator are = and :=.

Any assignment that changes an existing value (e. g. x := x + 1) is disallowed in purely functional languages. In functional programming, assignment is discouraged in favor of single assignment, also called name binding or initialization. Single assignment differs from assignment as described in this article in that it can only be made once, usually when the variable is created; no subsequent re-assignment is allowed. Once created by single assignment, named values are not variables but immutable objects.

In some languages, the symbol used is regarded as an operator (meaning that the assignment statement as a whole returns a value). Other languages define assignment as a statement (meaning that it cannot be used in an expression). Assignments typically allow a variable to hold different values at different times during its life-span and scope. However, some languages (primarily strictly functional languages) do not allow that kind of “destructive” reassignment, as it might imply changes of non-local state.

1 QUESTION 1 Computer-programming. Computer-programming is definitely an science and art, of giving a mechanism or computer, the directions or instructions to follow along with to resolve an issue or accomplish an activity. QUESTION 2 Variations BETWEEN EVENT-DRIVEN AND OBJECT-ORIENTED AND PROCEDURAL PROGRAMMING LANGUAGES. To say the least, in the event-Driven the flow of Control is dependent upon occasions triggered through the user, (click of the mouse), although Object-Oriented Programming necessitates the programmer to pay attention to the objects the program may use to complete its goal. Finally, in Procedural Oriented Programming, the programmer only focuses on the main tasks the program must perform step-by-step. The flow of control for that program is dependent upon occasions mostly triggered by users. That’s, execution is decided for instance with a user action for example click, keypress, or perhaps a message in the Operating-system (OS) or any other user. Visual Basics and Visual C++ are specifically made to facilitate event-driven programming and supply a built-in development atmosphere (IDE) that partly automates producing code.

What is an assignment in computer science example?

An assignment is a statement in computer programming that is used to set a value to a variable name . The operator used to do assignment is denoted with an equal sign (=). This operand works by assigning the value on the right-hand side of the operand to the operand on the left-hand side.

What does assignment mean in programming?

In order to change the data value stored in a variable , you use an operation called assignment. This causes the value to be copied into a memory location, overwriting what was in there before. Different values may be assigned to a variable at different times during the execution of a program.

What is assignment in Python?

An assignment statement evaluates the expression list (remember that this can be a single expression or a comma-separated list, the latter yielding a tuple) and assigns the single resulting object to each of the target lists, from left to right.

What is an assignment statement explain with an example?

An assignment statement gives a value to a variable . For example, x = 5; ... the variable may be a simple name, or an indexed location in an array, or a field (instance variable) of an object, or a static field of a class; and. the expression must result in a value that is compatible with the type of the variable .

What is an assignment in Java?

Assignment in Java is the process of giving a value to a primitive-type variable or giving an object reference to an object-type variable . The equals sign acts as assignment operator in Java, followed by the value to assign.

Introduction

People use computers every day at work, at school, and at home. Computers are used in factories to control how things are made and in offices to keep records. People also use computers for sending e-mail, writing reports, shopping, banking, listening to music, and playing games . The Internet , which is a huge network of linked computers, provides information from all over the world.

Types of Computers

Computers come in many forms. Supercomputers are very powerful and expensive computers that are used for complex work, such as forecasting the weather. Desktop personal computers, or PCs, are used for tasks at the office, at school, and at home. Laptops, notebooks, and tablet computers do the same things as PCs, but they are smaller and easy to carry. Personal digital assistants, or PDAs, are handheld computers. Some very small computers are used to control machines. They are built into such things as airplanes, robots in factories, cars, and even household appliances.

Computer Hardware and Software

A computer system requires both hardware and software. Hardware is the computer’s physical parts. Software is the programs, or instructions, that tell the hardware what to do.

All computers have the same basic hardware. The microprocessor is the computer’s “brain.” It is also called the CPU, or central processing unit. The microprocessor handles all the information that goes into and comes out of the computer. The memory is hardware that holds programs and data while the microprocessor uses it.

The programs and data are kept permanently on hardware called storage devices. Most computers have a storage device called a hard drive. The hard drive stores data on a metal disk inside the computer. Some storage devices put data on disks that can be easily moved from one computer to another. These disks include CDs and DVDs. They make it easy to share data.

Input and output devices are other types of hardware. Input devices let the user enter data or commands into the computer. Input devices include the keyboard and the mouse. Output devices let the user see or hear the results produced by the computer. Output devices include the monitor (or screen), printer, and speakers.

Communication, or network, devices connect computers to each other. They let people send data from one computer to another and connect to the Internet. Modems are communication devices that can send data through telephone wires or television cables. Some computers use wireless communication devices. They send data through the air using a small antenna.

Computer software is divided into two basic types—the operating system and application software. The operating system controls how the different parts of hardware work together. Application software gives the computer instructions for doing specific tasks, such as word processing or playing games.

How Computers Work

Most computers are electronic devices. This means that they work with electricity . All computer data is carried in tiny flows of electricity called electric currents. The microprocessor contains thousands or millions of tiny electronic parts called transistors. The transistors act as switches. They control how the electric currents flow.

Computers use these electric currents to represent the numbers 0 and 1. Computers use only these two numbers because transistors, like light switches, have only two states—they are either on or off. A transistor that is “on” represents one of the numbers. A transistor that is “off” represents the other. Computers use strings of 0s and 1s to stand for letters, sounds, and all of the other data they handle. For example, a computer stores the word dog as three numbers: 01100100 (d), 01101111 (o), and 01100111 (g).

Computers can understand only these patterns of 0s and 1s. All of the instructions that a computer follows have to be in this form. But people find it hard to work with long number patterns. So the people who write computer software, called computer programmers, have their own special languages. These include programming languages called BASIC, Java, and C++. The computer turns programming languages into the number patterns that it can understand.

Programmers use these languages to write instructions for the computer. The instructions tell the computer how to process data. The instructions consist of algorithms, which are a series of steps that are used to solve a problem.

An English inventor named Charles Babbage designed the first computer in the 1830s. It was mechanical, not electronic, because scientists did not yet know how electricity worked. The design called for more than 50,000 moving parts. The machine was designed to follow instructions that people entered using punched cards. It was so complex that Babbage never got it built. But it is still considered to be the first computer.

The first electronic computers were invented in the 1940s. In place of mechanical parts, they used electronic switching devices called vacuum tubes. These computers were so big that just one of them filled a whole room. They cost millions of dollars.

Computers improved after the transistor was invented in 1947. The transistor was an electronic switching device that was much smaller and worked better than a vacuum tube. By 1960 transistors had mostly replaced vacuum tubes in computers. The new computers were smaller and more affordable than before.

What is a Computer?

A computer is an electronic machine that processes raw data and outputs information. An electronic device that takes data as input and transforms it using a set of special instructions known as Programs to produce the desired output. A computer has an internal memory that stores data and instructions that are temporarily awaiting processing, as well as the intermediate result (information) before it is communicated to the recipients via the Output devices

What Does the Computer Require in Order to be Operational?

A Computer requires hardware devices and an operating system in order to be operational.

1. Hardware Devices

Monitor: It is a big television-like screen. It is an output device where you see what is happening on the computer.

Keyboard: It is an input device. It is a way of giving commands to a computer with the help of keys over it.

Central Processing Unit (CPU): It is a processing unit.It is considered the brain of the computer as it can’t perform any activity without CPU.

Mouse: It is an input device. This is the alternate method for cooperating with your PC. Most mice have two buttons — a right and a left button — and a looking over wheel.

Hardware Devices

2. Operating System (OS)

Operating System

PCs without an OS are precisely similar to TVs without a signal. They will turn on, yet you will be checking a clear screen out without any desire to collaborate with it. The most famous working framework is "Microsoft Windows," and it is used by most PC.

The OS acts as the sensory system of the PC, interfacing the computer processor to all the PC programs. The OS permits you to run other programs, work on projects, and do essentially all the other things that PCs are prepared to do.

There are a wide range of renditions of Microsoft Windows, and a new adaptation is delivered every several years.

How to Operate a Computer

There are three states in which a computer is at any given time.

OFF : This is precisely the exact thing it seems like: The PC is off, and no parts are running or working. The screen is dark (no pictures), there is no "humming" sound from the central processor, and the PC is inert to mouse developments or pressing keys on the keyboard. 

ON : When a PC is on, you ought to see pictures on the screen, conceivably hear a "buzzing" commotion coming from the central processor and the pointer on the screen ought to answer when you move the mouse.

Rest Mode : Most PCs have a mode called "Rest," in which the PC is on, yet has expected an energy-productive, insignificant power mode. To "wake" the PC, basically move the mouse around or press the spacebar on the console, and it will "awaken" and return to the identical spot that it was at the point at which it fell asleep.

Signing on Screen

When you turn the PC on, the PC will go through a progression of mechanized undertakings before it is prepared for you to associate with it; this cycle is called "startup." This cycle will endure somewhere in the range of one and two minutes. Assuming the PC is not working accurately, you might see a blunder message during startup.

After you sign on, the PC will show what is known as your work area inside a couple of moments to a couple of moments. Here you will see a computerized portrayal of something almost identical to real-life office space, complete with a work area, documents and record organizers, and a recycling bin.

Features of Computer

Below mentioned are some of the features of a computer..

When executing mathematical computations, a computer works significantly faster and more accurately than a human.

Speed of Computer

Calculations made by computers are always accurate. Data inaccuracy or consistency might lead to errors.

A computer contains internal storage for data called main memory. Data is also stored on removable media like CDs, pen drives, and other types of secondary storage.

Computer Memory

Reliability

When given the same set of data repeatedly, a computer will consistently provide the same output, demonstrating its dependability.

The computer completes every task automatically, that is, without human interaction.

Computer Automation

Drawbacks of Computer

Although using a computer has numerous benefits, there are also risks and drawbacks. If used improperly, computers can cause a number of health problems.

The computer is emotionless.

It can't function alone. It requires somebody to work on it and give it instructions.

The computer must be supplied with each command.

No choice can be made by a computer on its own.

What is a Machine?

A machine is a tool that facilitates our job.

It helps us save time and effort.

Humans are not as productive as machines .

Machine Examples Include the Following:

For enjoyment, people use televisions.

To iron the clothes, use an iron box.

An automobile is used for transportation.

Calling is done on a mobile device.

Mobile Device

Points to Remember 

Computer is an electronic machine.

The main components required for a computer are mouse, monitor and  keyboard.

The CPU is also known as the “Brain” of the computer.

OS stands for operating system.

The first screen you see when it starts is called the desktop.

FAQs on Introduction to Computer

1. Which OS does Apple use?

An Apple Computer is called a Macintosh (Mac). Its Operating System is OS X while other PCs use windows.

2. Do computers require the Internet to operate?

A computer does not need to access the Internet in order to run properly. The Internet is a way of connecting to other computer users. You can interface with the web utilizing a telephone line, a link association, or by utilizing a remote interfacing gadget (wi-fi). For most home PC clients, this is a paid help, however you can use the Web for free in a few public areas, similar to the library or a café. A PC will actually want to carry out most normal roles (play music, type records, alter pictures) and run programs without a Web association. Notwithstanding, to see a page or send an email, you will require a Web association. 

3. What “My Computer is Possessed!” means?

“My Computer is Possessed!” It is a common misconception that computers have “a mind of their own.” In spite of the fact that PCs can play out specific assignments significantly more effectively and quicker than people (like counting, performing numerical computations, and so on), they are, eventually, machines and can't have an independent mind. Any reasonable person would agree that the PC can do nothing that you don't advise it to do.

The Dawes Act, or General Allotment Act of 1887, was a law that allowed the U.S. government to take Native American tribal lands and divide them into 40 acre lots for individual Native Americans. The goal was to break up communal tribal lands and speed the assimilation of Native Americans into American society. The Dawes Act caused great suffering with much of the land winding up in the hands of white settlers.
