# std::list::resize

From cppreference.com
< cpp‎ | container‎ | list

[edit template]

void resize( size_type count, T value = T() ); |  | (until C++11)
void resize( size_type count ); | (1) | (since C++11)
void resize( size_type count, const value_type& value ); | (2) | (since C++11)

Resizes the container to contain `count` elements.

If the current size is greater than `count`, the container is reduced to its first `count` elements as if by repeatedly calling `pop_back()`.

If the current size is less than `count`, additional elements are appended and initialized with copies of `value`. | (until C++11)
If the current size is less than `count`, 1) additional value-initialized elements are appended 2) additional copies of `value` are appended | (since C++11)

### [edit] Parameters

count | - | new size of the container
value | - | the value to initialize the new elements with
Type requirements
- `T` must meet the requirements of `DefaultConstructible` and `MoveInsertable` in order to use overload (1).
- `T` must meet the requirements of `CopyInsertable` in order to use overload (2).

### [edit] Return value

(none)

### [edit] Complexity

Linear in the size of the container
