The program takes length and width values to calculate the area of a rectangle, a side value to calculate the area of a square, and base and height values to calculate the area of a triangle. It then displays the computed areas. It also describes a program that displays a user's name or "UNIDENTIFIED" when an enter button is clicked based on input.
