#include <iostream>

using namespace std;

void about(){

int MenuOne(){

int MenuProcessing(int MenuSize,int MenuSelection){

		while(MenuSize>b){

			}

			b++;
		}


int main(){
	start:
	int MenuSelection=0,EventStatis;
	about();
	MenuSelection=MenuOne();
	EventStatis=MenuProcessing(6,MenuSelection);
	if(EventStatis=0){
		goto start;
	}
    return 0;
}

so thats my code right.
where it says the function menuprocessing. I need a menuprocessing thingo cause i using lots and lots of menus.
so what i want is for where the

C++ Syntax (Toggle Plain Text)
		while(MenuSize>b){
			if(MenuSelection=b){
			}
 
			}
		while(MenuSize>b){
			if(MenuSelection=b){
			}

			}

is i want it to send it to the approbate selected menu thing.
so something like a function array....

C++ Syntax (Toggle Plain Text)
void MenuOne[1](){
}
void MenuOne[1](){
}

so when

C++ Syntax (Toggle Plain Text)

MenuMelection=b

it would go to the

C++ Syntax (Toggle Plain Text)
MenuOne[b]();
MenuOne[b]();

sucks that function arrays don't exist.

how would i go about doing something like that?

Re: Strange function problem!!

use a switch statement, then call the function you are after.

C++ Syntax (Toggle Plain Text)
switch(b){
case 1:
     menu1();
     break;
case 2:
     menu2();
     break;
case 3:
     menu3();
     break;
default:
     std::cout << "Invalid Choice!";
     break;
}
switch(b){
case 1:
     menu1();
     break;
case 2:
     menu2();
     break;
case 3:
     menu3();
     break;
default:
     std::cout << "Invalid Choice!";
     break;
}

I think that is what you are after,

Re: Strange function problem!!

Use a while loop instead of goto start.

Re: Strange function problem!!

Not to keep harping on this, but you really need to be careful about the difference between an assignment (=) and a comparison (==).

This means that you are assigning the value of the variable b to that of the variable MenuSelection.
[/icode] if(MenuSelection=b){ [/icode]

This means that you are comparing the variables MenuSelection and b
[/icode] if(MenuSelection == b){ [/icode]
