This document is a project report submitted by Shekh Mod. Usman Haider towards fulfilling requirements for a Bachelor's degree in Computer Application from Dezyne E ́cole College in Ajmer, India. The project involves developing a prime number checker using Visual Basic programming. The report acknowledges the guidance provided by Dezyne E ́cole College and necessary information and support for completing the project. It then provides code snippets for a program that takes integer input in a 3x3 array, checks if each number is prime by testing for divisors, and outputs the numbers in a second 3x3 array with prime numbers highlighted in red.
