How does a menu program work?
Short answer. It prints numbered choices, reads the number, and a switch runs that job.
What does case 2 calculate here?
The perimeter, 2 * (l + b).
Remember
| Print choices, read a number |
| switch runs the chosen job |
One program, many jobs. The user picks by number. Show the choices, then read the choice ch. Choice one finds the area. Choice two finds the perimeter. Remember. Print the choices and read a number. Switch runs the job.
