    Unhappy I need help with this last project! Credit Card Program!

    the account number to be validated.


    Once again, I am no longer trying to get a degree in this field but I really need to pass the class. Help would be very generous!

    Num = ccnum

    Count = 0

    While num > 0

    Count++

    Digit = num % 10 // get last digit

    If count % 2 == 1

    Total += digit

    Else

    Digit2 = digit * 2 //Preserve the value of digit

    If digit2 > 9

    Digit2 = 1 + digit2 % 10
    end if

    total += digit2

    end if

    Num /=10 // strips off last digit

    End while

    If digit = 6

    Type = “Discover”

    Else if digit = 5

    Type = “Mastercard”

    Else if digit = 4

    Type = “Visa”

    Else

    Type = “Unknown”

    If total % 10 = 0

    Card is valid

    Ok. Write that in C++, and make sure to indent it.

    Code:
    Num = ccnum
    
    Count = 0
    
    While num > 0
    
        Count++
    
         Digit = num % 10    // get last digit
    
        If count % 2 == 1
    
             Total += digit
    
        Else
    
             Digit2 = digit * 2   //Preserve the value of digit
    
             If digit2 > 9
    
                  Digit2 =  1 + digit2 % 10
             end if
    
              total += digit2
    
       end if
    
        Num /=10        // strips off last digit
    
    End while
    
    If digit = 6
    
       Type = “Discover”
    
    Else if digit = 5 
    
       Type = “Mastercard”
    
    Else if digit = 4
    
      Type = “Visa”
    
    Else
    
       Type = “Unknown”
    
    If total % 10 = 0
    
       Card is valid

    Alright, some indentation, and code tags are a good start. Now you just have to change from pseudocode to C++.

    What have you done so far. It's no point in someone here giving you advice on something you already have done, neither does it help to give advice on what you absolutely don't understand because you haven't got that far.

    So you need to translate your pseudo-code to C++, and you have ABSOLUTELY NO IDEA how to go about that, is that what you are saying?

    Did you look at the links by robwhit?

    He wants someone with the skill and generosity to do the code for him 'cause he doesn't want to learn C++ and he has to finish that thing for school. Or that's how I understand it :P

    I think you are right. I just wanted to get the original poster to say that...
