C++ Looping Problem

[khm3dia]

[/code]ive just started learning C++ at college and ive got this task to which means i have to create a program of how an actual ATM bank works. So far ive come up with this

#include <iostream>
#include <string>
#include <windows.h>
using namespace std;

int main(){

	int menuChoice=0;
	int PIN=1234; //PIN is the name of the variable
	bool pin=true; 
	bool isLooping = false;
	

	cout<<"\n\tWelcome and please insert your card"<<endl<<endl;
	Sleep(1500);
	system("CLS");
	
	while(isLooping==false){
		cout<<"\n\tEnter your PIN"<<endl;
		cin>>PIN;
		system("CLS");
		
	
		if(PIN  == 1234){
			cout<<"\t\nPlease choose one of the following options:"<<endl<<endl;
			cout<<"\t\n	1.Cash Out"<<endl;
			cout<<"\t\n	2.Statement"<<endl;
			cout<<"\t\n	3.Other options"<<endl;
			cin>>menuChoice;
			isLooping = true;
			system("CLS");
		}
		else if (PIN>=false){
			cout<<"\n\tIncorrect"<<endl;			
		}
		
		if(menuChoice==1){
			cout<<"\n\tYour balance today is: 9999.99\t"<<endl;
			Sleep(1500);

				cout<<"\n\tContinue?"<<endl;
				cout<<"\n\t >> 1.Yes <<"<<endl; 
				cout<<"\n\t >> 2.No <<"<<endl;
				cin>>menuChoice;
				system("CLS");
			

				if(menuChoice==1)
				{
					cout<<"\n\t >>Withdraw Amount<<"<<endl;
					Sleep(1000);
					cout<<"\n\t\t 1.5 Pounds"<<endl;
					Sleep(200);
					cout<<"\n\t\t 2.10 Pounds"<<endl;
					Sleep(200);
					cout<<"\n\t\t 3.20 Pounds"<<endl;
					Sleep(200);
					cout<<"\n\t\t 4.30 Pounds"<<endl;
					Sleep(200);
					cout<<"\n\t\t 5.40 Pounds"<<endl;
					Sleep(200);
					cout<<"\n\t\t 6.Triple Digit Value(000's)"<<endl;
					Sleep(2000);
				}
				
				if(menuChoice==2)
				{
					cout<<"\n\t Thank You for using our services"<<endl;
					system("\n\tpause");
					//cin>>menuChoice;
				}
				return 0;
				
		}

			if(menuChoice==2){
				cout<<"\n\tPrinting Statement"<<endl;
				Sleep(1500);
				cout<<"\n\tPrinting Complete"<<endl;
				Sleep(1500);
				cout<<"\n\tContinue?"<<endl;
				cout<<"\n\t 1.Yes"<<endl; 
				cout<<"\n\t 2.No"<<endl;
				cin>>menuChoice;
				system("CLS");
				

				

				/*if(menuChoice==1){
					cout<<"\t\nPlease choose one of the following options:"<<endl<<endl;
					cout<<"\t\n	1.Cash Out"<<endl;
					cout<<"\t\n	2.Statement"<<endl;
					cout<<"\t\n	3.Other options"<<endl;
					cin>>menuChoice;
					//isLooping = true;//
					system("CLS");
					}*/

			}
	}


		cin.get();
		cin.get();
}

/*

while(){

	
}


} */

what i want to do is after the part where it says continue and you either press 1 or 2 it should take you back to the main menu instead of having to recode everything again.

i know i need to use some sort of a loop but i dnt know how...any ideas??? also can you guys make it quite easy to understand.

[CallMeCrazy]

Can you recopy your code back here into code tags so it is not a pain to look at >.<?
hey are at the bottom, and they end up as: [codea] Your code goes here [/codea], but without the a's in them.

[khm3dia]

I dont really get what you mean

[freddy92]

Just highlight your code and click the "<>" button under Format.

[devonrevenge]

you frm brighton?? its ur tag see.

[devonrevenge]

kay what you can do is have lots of functions, so you can call them in a loop in main, you can have a loop within a loop too.

soo

function 1 

function 2

main ()
{


while (running = true)
{

menu

function 1


if(input==2)
{


function 2

}
input = 0


}




}

my psudo code is a bit lazy but you see what i did there, you can manage quite a lot with loos

loops even

I think what devonrevenge is trying to say is use a switch statement that has a case for each menu option. From each case call a function that carries out that menu option. That will cut down on repeatedly testing the menu option variable.

Also put the whole into a loop like this:

#include <iostream>
#include <locale>  //need this for std::toupper

//using namespace std   <--- don't do this

using std::cin;   //either do this, or put std:: before each std thing
using std::cout;  //I do this for things used a lot
using std::endl;  //then use std:: for things that are not

//Put function declarations for each menu option  here


int main() {

     bool Quit = false;
     char answer = 'N';

    while(!Quit) {

           //your code here

//function to show the menu
//get the menu option
//switch statement to process menu options

           cout << "Do you want to Quit? Y or N" << endl;
           cin >> answer;
          
           answer = std::toupper(answer);  //avoids testing answer twice
           if(answer == 'Y')  //test variable once
                 Quit = true;
    }

return 0;  //if all is well, something else if not
} //end of main

//definitions of functions here
