c++ - Copying std::vector: prefer assignment or std::copy ...
You can't, for example, use the assignmentoperator to copy from a std::list to a std::vector, or from one portion of a std::vector to another portion of the same std::vector. – Benjamin Lindley Commented Sep 15, 2015 at 18:10
c++ - Why does std::vector have two assignment operators ...
Since 2011, we have both copy and move assignment. However, this answer argues quite convincingly that, for resource managing classes, one needs only one assignment operator. For std::vector, for example, this would look like. vector& vector::operator=(vector other) { swap(other); return*this; }
1) Copy assignmentoperator. Replaces the contents with a copy of the contents of other . If std:: allocator_traits < allocator_type > :: propagate_on_container_copy_assignment :: value is true , the allocator of * this is replaced by a copy of other .
std::vector<T,Allocator>:: assign. Replaces the contents of the container. 1) Replaces the contents with count copies of value value. 2) Replaces the contents with copies of those in the range [first,last). The behavior is undefined if either argument is an iterator into *this. This overload has the same effect as overload (1) if InputIt is an ...
vector - C++ Users
vector& operator= (initializer_list<value_type> il); Assign content Assigns new contents to the container, replacing its current contents, and modifying its size accordingly.
vector::operator= and vector::operator[ ] in C++ STL
vector::operator= vector::operator[] Purpose: Assigns one vector to another: Accesses elements of the vector: Usage: v1 = v2; v[i]; Functionality: Copies all elements from one vector to another: Retrieves or modifies an element at a specific index: Return Type: vector& T& (reference to the element type) Parameters: const vector& (another vector ...
Copy assignment operator - cppreference.com
A copyassignmentoperator is a non-template non-static member function with the name operator= that can be called with an argument of the same class type and copies the content of the argument without mutating the argument. Syntax. For the formal copy assignment operator syntax, see function declaration.
vector - C++ Users
Assignvector content. Assigns new contents to the vector, replacing its current contents, and modifying its size accordingly. C++98. C++11. In the range version (1), the new contents are elements constructed from each of the elements in the range between first and last, in the same order.
Copy Constructors and Assignment Operators - Stanford University
C++ handles object copying and assignment through two functions called copy constructors and assignmentoperators. While C++ will automatically provide these functions if you don't explicitly define them, in many cases you'll need to manually control how your objects are duplicated.

Similarly, C++ provides operators for the compound assignments -=, *=, and /=. The function names corresponding to them are operator+= , etc. For operations between pairs of vectors, the meanings of ``add and assign'' and ``subtract and assign'' are natural.
