Question

If for instance you have a std::vector<MyClass>, where MyClass has a public method: bool isTiredOfLife(), how do you remove the elements that return true?

Answer 1

I prefer remove_if

v.erase(remove_if(v.begin(), v.end(),                   mem_fun_ref(&MyClass::isTiredOfLife)),          v.end()); 

remove_if returns an iterator pointing after the last element that’s still in the sequence. erase erases everything from its first to its last argument (both iterators).
