I ran out of room due to my cheesy border and such.

I apologize in advance if my method is awful, that's why I came here.

I cut a ton of stuff out which served as an introduction, as well as some more "pages" may have messed it up, so try not to nitpick { and such.

I'm trying to make a base menu that can go out to single pages, and possibly back to the main menu, and so on.

147 is a complete shot in the dark. I'm lost when it comes to starting over at main menu.

No one? :-(

I am far from being even close to an expert, but I'm pretty sure that if you want the program to keep running, you don't

return 0;

you tell it to return to wherever you want it to go, in this case, I would guess

return choice;

or whatever your main page reference is. If your wanting to return to main, I'd guess that you would have to add something to your code to reference from return that would allow you to pop back in there, and then throw in an option to choose, say a number, that would then return zero, and then exit the program. Just a guess, good luck!

void menu2()
{
//menu stuff here//
//....
//....
}


void menu1()
{
//menu stuff here//
//....
//....
if (choice == ....)
menu2();
}

int main()
{
menu1();
return 0;
}

Smac: so menu 1 is the base? Since you're allowing it to return 0 and end the program? Why does the first bit not have an if?
Are you writing it essentially backwards to make it work? Any help or details appreciated


Thanks xanthian, I'll try that too

I (think I) followed what you gave me, Smac89, but I get an error at the if statement in "menu 1". It says the identifier menu is not found.

Try menu2(); instead of menu(2);

Thanks plexus! I figured that typo out shortly after. :P

The problem now is, once I leave menu 1, I can't go back to it from another..

You cant call menu1() from any of the other menu#() functions because it's defined later.
Either you put it at the top of the function definitions or create function prototypes (which is the cleaner way).

But beware: don't call menu1() from one of the other menu functions because you would create some kind of weird indirect recursion like:
menu1() -call-> menu2() -call-> menu1() -call-> menu3() -....

Better do something like:
menu1() -call-> menu2() -return to-> menu1() -call-> menu3() -...

That is where function headers come in handy. Using these, you can call a function without having it's entire declaration above the code calling it. This is a compile time operation.

I scattered the declarations so you know that is doesn't matter the order you do them in as long as you declare them
