How to keep player scores and create a basic menu in a C++ console game?

I have to create a C++ game that is 500 lines of code. I'm at 250 right now and I was wondering how do you create a basic menu that would allow the user to push either 1 for highest score,2. to play game, and 3 for help which would give the rules of the game? Would it be using if/else statements or functions? Can anyone point me in the right direction

How to keep player scores and create a basic menu in a C++ console game?
I think it might be better to use a switch statement for the menu.





1 for highest score,


2. to play game,


3 for help which would give the rules of the game





It'd be best for the menu to be it's own function.





int main()


{





menu();





return 0;


}





Menu will be called then the switch will do a different case depending on the user's input.
