lab 21
Hello everyone! Lab 21 was one of the challenging labs that we had to do during the 2nd marking PD. For this lab, we had to validate everything that the user inputs. It included name, address, zip code, phone number and credit card number. And for this, we had to validate it. So it for the phone number it needs to be certain digit and for a credit card, it must be certain characters long. this was hard because or special instruction was that credit card number must be equal to 16+ when u add up all the 16 character number also it must end with an even number. But it was done. That's all for this lab.
