Lab 2

Write a Pascal program to display a menu and request from the user their choice.

If they enter an 'A' then request from the user the radius for a circle. The program
should calculate and print the circumference and the area of the circle. Echo print the
radius.

If they enter a 'B' then request from the user the two sides of a rectangle.  The program
should calculate and print the perimeter and the area of the rectangle.  Echo print the
two sides.

The program should only handle one set of data.  No loop is required.  Make the
output readable and in report form.
