C++ Syntax (Toggle Plain Text) 
  1. #include <iostream>
  2. #include <windows.h>
  3. using namespace std;
  4.  
  5. void about(){
  6. 		cout<<"Expence-List 14/10/2008:"<<endl
  7. 		      <<"Brought to you by www.******.com"<<endl
  8.     		      <<"Programmed by **********."<<endl;
  9. 		Sleep(4000);
  10. 		system("cls");
  11. 	}
  12.  
  13.  
  14. int MenuOne(){
  15. 		int MenuSelection=0;
  16. 		cout<<"What would you like to do?"<<endl
  17. 			<<"--------------------------------"<<endl
  18. 			<<"1. Create a new expence list."<<endl
  19. 			<<"2. Edit a previous expence list."<<endl
  20. 			<<"3. View a saved expence list."<<endl
  21. 			<<"4. Settings"<<endl
  22. 			<<"5. About."<<endl
  23. 			<<"6. Close Program"<<endl
  24. 			<<"--------------------------------"<<endl
  25. 			<<endl;
  26. 		cin>>MenuSelection;
  27. 		system("cls");
  28. 		return MenuSelection;
  29. 	}
  30.  
  31.  
  32. int MenuProcessing(int MenuSize,int MenuSelection){
  33. 		int b=1;
  34. 		if(MenuSelection>MenuSize){
  35. 			cerr<<"You've entered an invalid option!"<<endl
  36. 				<<"Try again!."<<endl;
  37. 			Sleep(2000);
  38. 			system("cls");
  39. 			return 0;
  40. 		}
  41.  
  42. 		while(MenuSize>b){
  43. 			if(MenuSelection=b){
  44. 			}
  45.  
  46. 			}
  47.  
  48. 			b++;
  49. 		}
  50.  
  51.  
  52. int main(){
  53. 	start:
  54. 	int MenuSelection=0,EventStatis;
  55. 	about();
  56. 	MenuSelection=MenuOne();
  57. 	EventStatis=MenuProcessing(6,MenuSelection);
  58. 	if(EventStatis=0){
  59. 		goto start;
  60. 	}
  61.     return 0;
  62. }

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) 
  1. 		while(MenuSize>b){
  2. 			if(MenuSelection=b){
  3. 			}
  4.  
  5. 			}
is i want it to send it to the approbate selected menu thing.
so something like a function array....

C++ Syntax (Toggle Plain Text) 
  1. void MenuOne[1](){
  2. }

so when
C++ Syntax (Toggle Plain Text) 
  1. MenuMelection=b
it would go to the
C++ Syntax (Toggle Plain Text) 
  1. MenuOne[b]();

sucks that function arrays don't exist.

how would i go about doing something like that?

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

C++ Syntax (Toggle Plain Text) 
  1. switch(b){
  2. case 1:
  3.      menu1();
  4.      break;
  5. case 2:
  6.      menu2();
  7.      break;
  8. case 3:
  9.      menu3();
  10.      break;
  11. default:
  12.      std::cout << "Invalid Choice!";
  13.      break;
  14. }

I think that is what you are after,
Chris

Use a while loop instead of goto start.

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]
