void erase_if ( std:: basic_string < CharT, Traits, Alloc > & c, Pred pred ) ; |
(library fundamentals TS v2) | |
Erases all elements that satisfy the predicate pred from the container. Equivalent to c. erase ( std:: remove_if ( c. begin ( ) , c. end ( ) , pred ) , c. end ( ) ) ; .
Parameters
| c | - | container from which to erase |
| pred | - | predicate that determines which elements should be erased |
Complexity
Linear.
Example
#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"
