C Bitwise OR and assignment operator
The Bitwise OR and assignment operator (|=) assigns the first operand a value equal to the result of Bitwise OR operation of two operands. The Bitwise OR operator (|) is a binary operator which takes two bit patterns of equal length and performs the logical OR operation on each pair of corresponding bits. It returns 1 if either or both bits at ...
Bitwise Operators in C
Bitwise Operators in C. In C, the following 6 operators are bitwise operators (also known as bit operators as they work at the bit-level). They are used to perform bitwise operations in C. The & (bitwise AND) in C takes two numbers as operands and does AND on every bit of two numbers. The result of AND is 1 only if both bits are 1.
Unclear about the use of Bitwise AND assignment
The &= and the ++ together are the same as X = (X + 1) % 1024; but can be computed faster by the CPU. 1024-1 is 11 1111 1111 in binary, so for numbers where X < 1024, a bitwise AND will have no effect (since any bit & 1 = the same bit). Interesting things only start to happen where X ≥ 1024, so let's consider the iteration of the loop where X ...
Bitwise operations in C
C provides a compound assignment operator for each binary arithmetic and bitwise operation. Each operator accepts a left operand and a right operand, performs the appropriate binary operation on both and stores the result in the left operand. [6] The bitwise assignment operators are as follows.
C Bitwise Operators: AND, OR, XOR, Complement and Shift Operations
The output of bitwise AND is 1 if the corresponding bits of two operands is 1. If either bit of an operand is 0, the result of corresponding bit is evaluated to 0. In C Programming, the bitwise AND operator is denoted by &. Let us suppose the bitwise AND operation of two integers 12 and 25. 12 = 00001100 (In Binary) 25 = 00011001 (In Binary)
Bitwise AND operator in Programming
The Bitwise AND operation (&) is a binary operation that operates on each bit of its operands independently. It returns a new value where each bit of the result is determined by applying the AND operation to the corresponding bits of the operands. The truth table for the Bitwise AND operation is as follows: A. B. A AND B.
Assignment Operators in C
Simple assignment operator. Assigns values from right side operands to left side operand. C = A + B will assign the value of A + B to C. +=. Add AND assignment operator. It adds the right operand to the left operand and assign the result to the left operand. C += A is equivalent to C = C + A. -=.
Assignment operators
Assignment performs implicit conversion from the value of rhs to the type of lhs and then replaces the value in the object designated by lhs with the converted value of rhs. Assignment also returns the same value as what was stored in lhs (so that expressions such as a = b = c are possible). The value category of the assignment operator is non ...
C Assignment Operators
Syntax. The assignment operators in C can both transform and assign values in a single operation. C provides the following assignment operators: | =. In assignment, the type of the right-hand value is converted to the type of the left-hand value, and the value is stored in the left operand after the assignment has taken place.
Operators in C
Operators are symbols used for performing some kind of operation in C. There are six types of operators, Arithmetic Operators, Relational Operators, Logical Operators, Bitwise Operators, Assignment Operators, and Miscellaneous Operators. Operators can also be of type unary, binary, and ternary according to the number of operators they are using.
C Operator Precedence
They are derived from the grammar. In C++, the conditional operator has the same precedence as assignment operators, and prefix ++ and -- and assignment operators don't have the restrictions about their operands. Associativity specification is redundant for unary operators and is only shown for completeness: unary prefix operators always ...
Precedence and order of evaluation
In the first expression, the bitwise-AND operator (&) has higher precedence than the logical-OR operator (||), so a & b forms the first operand of the logical-OR operation.In the second expression, the logical-OR operator (||) has higher precedence than the simple-assignment operator (=), so b || c is grouped as the right-hand operand in the assignment.
Bitwise operator programming exercises and solutions in C
List of bitwise operators exercises. Below is a set of programming exercises that can be used by a beginner or an intermediate programmer to master their skills on bitwise operator. Write a C program to check Least Significant Bit (LSB) of a number is set or not. Write a C program to check Most Significant Bit (MSB) of a number is set or not.
Bitwise AND Operator (&) in C
Bitwise operators in C allow low-level manipulation of data stored in computer's memory. Bitwise operators contrast with logical operators in C. For example, the logical AND operator (&&) performs AND operation on two Boolean expressions, while the bitwise AND operator (&) performs the AND operation on each corresponding bit of the two operands.
Bitwise Operators in C with Examples
Bitwise operators perform operations on bit level. For example, a bitwise & (AND) operator on two numbers x & y would convert these numbers to their binary equivalent and then perform the logical AND operation on them. C language supports following Bitwise operators: 1. Bitwise & (AND) operator.
What are bitwise shift (bit-shift) operators and how do they work?
The Bitwise operators are used to perform operations a bit-level or to manipulate bits in different ways. The bitwise operations are found to be much faster and are some times used to improve the efficiency of a program. Basically, Bitwise operators can be applied to the integer types: long, int, short, char and byte. Bitwise Shift Operators
C++ Bitwise AND Assignment (&=) Operator
In C++, Bitwise AND Assignment Operator is used to compute the Bitwise AND operation of left and right operands, and assign the result back to left operand. The syntax to compute bitwise AND a value of 2 and value in variable x, and assign the result back to x using Bitwise AND Assignment Operator is. x &= 2.
Using bitwise operators for Booleans in C++
2. Using bitwise operations for bool helps save unnecessary branch prediction logic by the processor, resulting from a 'cmp' instruction brought in by logical operations. Replacing the logical with bitwise operations (where all operands are bool) generates more efficient code offering the same result.

Bitwise assignment operators. Similar to the arithmetic assignment operators, C++ provides bitwise assignment operators in order to facilitate easy modification of variables.

Left Shift and Right Shift Operators in C/C++
The left shift (<<) is a binary operator that takes two numbers, left shifts the bits of the first operand, and the second operand decides the number of places to shift. In other words, left-shifting an integer "a" with an integer "b" denoted as '(a<<b)' is equivalent to multiplying a with 2^b (2 raised to power b). Syntax.
objective c
assigns to w3 the value of w1 bitwise ANDed with the constant 3. This has the same ffect of setting all the bits in w, other than the rightmost two bits to 0 and preserving the rightmost two bits from w1. As with all binary arithmetic operators in C, the binary bit operators can also be used as assignment operators by adding an equal sign.
