std::{{{1}}}::assign
From cppreference.com
void assign( size_type count, const T& value ); |
(1) | (since {std}) |
template< class InputIt > void assign( InputIt first, InputIt last ); |
(2) | (since {std}) |
void assign( std::initializer_list<T> ilist ); |
(3) | (since {std}) |
Replaces the contents of the container.
1) Replaces the contents with
count
copies of value value
2) Replaces the contents with copies of those in the range
[first, last)
3) Replaces the contents with the elements from the initializer list
ilist

Parameters
count | - | the new size of the container |
value | - | the value to initialize elements of the container with |
first, last | - | the range to copy the elements from |
ilist | - | initializer list to copy the values from |

Complexity
1) Linear in
count
2) Linear in distance between
first
and last
3) Linear in ilist.size()
Example
The following code uses assign
to add several characters to a std::{{{1}}}<char>:
Run this code
#include <{{{1}}}> #include <iostream> int main() { std::{{{1}}}<char> characters; characters.assign(5, 'a'); for (char c : characters) { std::cout << c << '\n'; } return 0; }
Output:
a a a a a
