void assign( size_type count, const T& value );	(1)
template< class InputIt > void assign( InputIt first, InputIt last );	(2)

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)

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
Type requirements
- InputIt must meet the requirements of InputIterator.

Complexity

1) linear in count

2) linear in distance between first and last

Example

The following code uses assign to add several characters to a std::list<char>:

#include <list>
#include <iostream>
 
int main()
{
    std::list<char> characters;
 
    characters.assign(5, 'a');
 
    for (char c : characters) {
        std::cout << c << '\n';
    } 
 
    return 0;
}

Output:

a
a
a
a
a
