void push_back( const T& value );
void push_back( T&& value );		(since C++11)

Appends the given element value to the end of the container.

All iterators are invalidated. No references are invalidated.

Parameters

value

-

the value of the element to append

Requirements

1) value shall be CopyInsertable

2) value shall be MoveInsertable

Return value

(none)

Complexity

Constant.

Example

The following code uses push_back to add several integers to a std::deque<int>:

#include <deque>
#include <iostream>
 
int main()
{
    std::deque<int> numbers;
 
    numbers.push_back(42);
    numbers.push_back(314159); 
 
    for (int i : numbers) { // c++11 range-based for loop
        std::cout << i << '\n';
    } 
 
    return 0;
}

Output:

42
314159
