.

The signature of the predicate function should be equivalent to the following:

bool pred(const Type &a);

The signature does not need to have const &, but the function must not modify the objects passed to it.
The type Type must be such that an object of type forward_list<T,Allocator>::const_iterator can be dereferenced and then implicitly converted to Type. ​

#include <forward_list>

int main()
{
    std::forward_list<int> l = { 1,100,2,3,10,1,11,-1,12 };
 
    l.remove(1); // remove both elements equal to 1
    l.remove_if([](int n){ return n > 10; }); // remove all elements greater than 10
 
    for (int n : l) {
        std::cout << n << ' ';
    }
    std::cout << '\n';
}

Output:

2 3 10 -1
