Try This.....Works fine for me...

Try This.....Works fine for me...You forgot to define the function exit();......

Im have trouble complete on what i have. Looking for some idea's I'm getting a exit error and don't know what to do? Please Help

With what? Do you have a problem? Did you tell us what that problem is? If you did, I missed it somewhere in the explanation.

Please use [code] tags.....

Why? If you don't format anything, it looks the same with or without CODE tags. Unreadable. So always format your code

Also, here we don't post answers to questions. We help them find their own answers. They learn more.

commented: Yes! +20
commented: Not sure what the down votes were about. This post seems good to me. +11

okay thanks for the help. that was stupid of me. Now my problem is i can't get my switch to call out my funtions. any ideas?

The lines below are probably causing the issue...your do while loop is not set up that great...also you are asking for the same input twice (Unnecessary)...
you ask for choice input here

cin >> choice;
while (choice < 'A' || choice > 'C')

and here

cout << " Please make a choice in the range";
cout << " of A through B:";
cin >> choice;

If you delete your do while loop, you will notice it runs fine....In other words re-think and redo you looping system...:)

Thanks again for the help. I ended up figureing it out. My next problem is i need to muliples of $20 and this is what i have

So i have continued from my last post and im completely screwed up. Things that i have tried to add is to keep a TOTAL BALANCE and i still need some help on the multipule of 20 withdrawal.

// This is a program that is an ATM.
#include <iostream>
#include <cstdlib>
#include <iomanip>
using namespace std;

// These are function prototypes
void welcome();
void menu();
double amountDeposit ();
void amountWithdrawal();
double finalBalance ();
void exit();

// This the main function that will operate all other funtions.
int main ()

{
char choice;
double deposit,totalBalance;
	  
welcome();
do 
{

menu();
cin >> choice;
while (choice < 'A' || choice > 'C')
{
cout << " Please make a choice in the range";
cout << " of A through C:";
cin >> choice;
}
switch (choice)
{
case 'a' :
case 'A' : exit();
break;
case 'b' :
case 'B' : amountDeposit();
		   cout << "You deposited $ " << amountDeposit() << "." <<  finalBalance () << "." << endl;
           break;
case 'c' :	
case 'C' : amountWithdrawal();
break;
}
} while ( choice != 'A');




return 0;
}

}


system ("PAUSE");
system ("cls");
}

double finalBalance (double totalBalance)
{
	double balance = 800,
	       totalbalance;
	totalBalance = balance + amountDeposit();
	return (totalbalance);
}
	

// This is the exit funtion
void exit ()
