| template< class InputIt > void assign( InputIt first, InputIt last ); |
(2) | |
| void assign( std::initializer_list<T> ilist ); |
(3) | |
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 |
| Type requirements | ||
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
