template<class CharT,class Traits,class Alloc,class Pred> void erase_if(std::basic_string<CharT, Traits, Alloc>& c, Pred pred); | (library fundamentals TS v2) | |
Erases all elements that satisfy the predicatepred from the container. Equivalent toc.erase(std::remove_if(c.begin(), c.end(), pred), c.end());.

[edit]Parameters
| c | - | container from which to erase |
| pred | - | predicate that determines which elements should be erased |
[edit]Complexity
Linear.
[edit]Example
Run this code
#include <experimental/string>#include <iomanip>#include <iostream> int main(){std::string data{"1337!p_C00L_<a-_HACKER_!@s_(!s#@_w^o%r*d#42"};std::cout<<"Original string: "<<std::quoted(data)<<'\n';auto crack=[](auto O){return'`'^('`'& O);}; std::experimental::erase_if(data, crack);std::cout<<"After erase_if: "<<std::quoted(data)<<'\n';}
Output:
Original string: "1337!p_C00L_<a-_HACKER_!@s_{!s#@_w^o%r*d#42"After erase_if: "password"[edit]See also
