Thread: ATM C++ Case Help.

Can someone please assist me, Im having difficulties with this switch statement, instructions are below.

If the user enters 2 to make a withdrawal, the user will be prompted to enter an amount or type
0 (zero) to return to the main menu.
a. If the withdrawal amount is greater than the account balance, the screen will display an
error message stating this and prompts them to enter a smaller amount.
b. If the withdrawal amount can be satisfied, carry out the transaction, display the new balance and return to the main menu.

Code:

        case 2: cout << "Please Enter sum you wish to withdraw from account" << endl;
            cin >> withdraw;
        
        if ( withdraw > balance){
           cout << "Value Exceeds Current balance \n" << endl;
           cout << "please enter new amount or type 0 to return to menu" <<endl;
           cin >> withdraw;
           }   
               if (input == 0){
               return 0;
               }
     
            balance = balance - withdraw;{
            cout << " You Have Withdrawn" << withdraw << "From your Accout" << endl;
            cout << " Balance is now" << balance << endl;
        }
          break;

Do you have some kind of question?

How to i get it to clear screen and return to the menu when 0 is entered ?

im trying to do an if statement but i dont know how to write it... if withdrawal > balance it should say it exxceeds amount and it should prompt the user to enter a new amount or 0 to return to the menu. if 0 is entered i want it to clear screen and start from the top.

Code:

  cout << "      MENU         ";
  cout << "1. Balance inquiry \n";
  cout << "2. Withdrawal \n ";
  cout << "3. Deposit \n";
  cout << "4. Type -69 to Exit";
  cout << " type 0 to return to menu";
  cout << "Please Enter Choice \n";
  cin >> input;
  
  while (input != -69){

How can I tell? The snippets haven't shown enough content to really show anything about your program.

I recommend you post your complete program, then maybe someone can be of assistance.

But as far as to clear the screen, there is really no standard way to accomplish this. There are operating system specific, or other libraries that can accomplish this but I recommend you just stick to standard functions and not worry about clearing the screen.

this is it..its very messy .

Yes, very. Maybe you should think about cleaning it up. In the process you may also want to consider the use of functions and some of the different loop constructs. And as already pointed out you need to sit down, away from the computer, and actually plan out the functionality of your program. And remember before you even start writing your program you must throughly understand the problem. The use of flow charts and pseudo code should be of a great help.

Ok, i going to draw up a flow chart and figure it out
