Defined in header <experimental/string>
template< class CharT, class Traits, class A, class U > void erase( std::basic_string<CharT, Traits, A>& c, const U& value );		(library fundamentals TS v2)

Erases all elements that compare equal to value from the container. Equivalent to c.erase(std::remove(c.begin(), c.end(), value), c.end());.

Parameters

c	-	container from which to erase
value	-	value to be removed

Complexity

Linear.

Example

Run this code

#include <experimental/string>
#include <iostream>
 
int main()
{
    std::string data{"$$P$A$S$S$$W$O$R$$D$"};
    std::cout << data << '\n';
    auto crack{'$'};
    std::experimental::erase(data, crack);
    std::cout << data << '\n';
}

Output:

$$P$A$S$S$$W$O$R$$D$
PASSWORD
