struct with member function as parameter

Question

I am a beginner in C++ and stack exchange. I am working on an Interface class that gets keyboard input and checks to see whether it is correct through looping through an arr

Answer 1

You should do something as shown below:

#include 
struct Input_Interface {
    struct command_output {
      std::string command;
      void (*output_function)();
    };

    static void Clear();
    static void Quit_loop();
};

int main() {
    Input_Interface::command_output t = {"CLEAR", Input_Interface::Clear};
    return 0;
}

Although I would suggest using a functor object over function pointer.
