Defined in header <experimental/forward_list> | ||
template<class T,class A,class U> void erase(std::forward_list<T, A>& c,const U& value); | (library fundamentals TS v2) | |
Erases all elements that compare equal tovalue from the container. Equivalent toc.remove_if([&](auto& elem){return elem== value;});.

[edit]Parameters
| c | - | container from which to erase |
| value | - | value to be removed |
[edit]Complexity
Linear.
[edit]Example
Run this code
#include <experimental/forward_list>#include <iostream> auto show=[](constauto& container){for(auto e: container)std::cout<< e;std::cout<<'\n';}; int main(){std::forward_list<int> data{1,1,1,4,1,1,1,2,1,1,1}; show(data); std::experimental::erase(data,1); show(data);}
Output:
1114111211142
Notes
Unlikestd::forward_list::remove, this function template accepts heterogeneous types and does not force a conversion to the container's value type before invoking the== operator.
