C++ for each, pulling from vector elements

Question

I am trying to do a foreach on a vector of attacks, each attack has a unique ID say, 1-3.

The class method takes the keyboard input of 1-3.

C++ does not have the for_each loop feature in its syntax. You have to use c++11 or use the template function std::for_each.

struct Function {
    int input;
    Function(int input): input(input) {}
    void operator()(Attack& attack) {
        if(attack->m_num == input) attack->makeDamage();
    }
};
Function f(input);
std::for_each(m_attack.begin(), m_attack.end(), f);
