# std::list::push_back

From cppreference.com
< cpp‎ | container‎ | list

[edit template]

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.

### [edit] 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).

### [edit] Return value

(none)

### [edit] Complexity

Constant.

### [edit] Exceptions

If an exception is thrown, this function has no effect (strong exception guarantee).

### [edit] Example

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

Run this code

    #include <list>
    #include <iostream>

    int main()
    {
        std::list<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
