std::list::push_back

From cppreference.com
< cpplrm; | containerlrm; | list

void push_back( const T& value );
(1)
void push_back( T&& value );
(2) (since C++11)

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

1) The new element is initialized as a copy of value.
2) value is moved into the new element.

No iterators or references are invalidated.

Parameters

value - the value of the element to append
Type requirements
-
T must meet the requirements of CopyInsertable in order to use overload (1).
-
T must meet the requirements of MoveInsertable in order to use overload (2).

Return value

(none)

Complexity

Constant.

Exceptions

If an exception is thrown (which can be due to Allocator::allocate() or element copy/move constructor/assignment), this function has no effect (strong exception guarantee).


Example

#include <list>
#include <iostream>
#include <iomanip>

int main()
{
    std::list<std::string> numbers;

    numbers.push_back("abc");
    std::string s = "def";
    numbers.push_back(std::move(s));

    std::cout << "list holds: ";
    for (auto&& i : numbers) std::cout << std::quoted(i) << ' ';
    std::cout << "\nMoved-from string holds " << std::quoted(s) << '\n';
}

Output:

list holds: "abc" "def" 
Moved-from string holds ""
