# std::forward_list::resize

From cppreference.com
< cpp‎ | container‎ | forward list

[edit template]

void resize( size_type count ); | (1) |
void resize( size_type count, const value_type& value); | (2) |

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`,

1) additional value-initialized elements are appended
2) additional copies of `value` are appended

### [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
