This document provides instructions for four Visual Basic programming exercises involving loops. The first three exercises involve generating integers from 1 to 10 using different loop structures and displaying the results in message boxes. The fourth exercise involves programming a button to check if a number entered in a text box is a prime number and displaying "Yes" or "No" accordingly in a message box.
