Defined in header <experimental/string>
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 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.
