Return to last function

[Ch1156]

I have my code that allows you to save from 3 different functions, depending on which one your in, and i can use the return statement to return back to the function but is there a way i can return to the last function without knowing what that function is?

Can you clarify a little more. Give names of the functions, or better yet, share the function codes and specify where you want to "return" to or how exactly you want the code to work.

[Ch1156]

I want it to return whatever function that the user was last in, i dont want to hard code a certain function, i want the program to know what function i was last in and return to it.

I want to return from save.

My code

#include <iostream>
#include <string>
#include <ctime>
#include <random>
#include <fstream>

using namespace std;

class Vars

    public:
        void Battle();

        Vars()
        {
            PHealth = 100;
            EHealth = 100;
            XP = 0;
        }
    private:
        int PHealth; //Player Health
        int EHealth; //Enemy Health
        int XP;
};

C++ functions act like that by default...But since you're calling Save() at the end of the function, it's like the Save returns you back to main. Consider using a loop.

Edit: Also, never ever ever ever ever call main(). That is a horrible programming technique and should always always be avoided. You need to learn loops.
