1) IF or Case - Tall or Short Program
a) When asked most older people can easily state their height in terms of inches or feet and
inches (imperial system). Now the standard is to use the metric system. On our drivers
license our height is stated in centimeters. Note that 1 inch = 2.54 centimeters.

which requests a person's name and their height in inches. The program would then print
their height in centimeters along with the person's name and other identifying information.
Program Specifications:
For example: Please enter your name. Hi Marie!
What is your height in inches? 70

golf has many
rules and
regulations as

main focus of
golf is the final
score that was

holes even exceed a par 5.
For example the first hole, is a par 4. The player, to get a good score, must try to use 4 or
less strokes to get the golf ball into the hole.

3-4= -1. The player is 1 under par. This is termed a birdie. An eagle is two under par.
If the player took 5 shots to get the golf ball into the hole. The player is 1 over. Again Score
- Par, 5 -4 =1. This is termed a boggie. Two over is termed a double boggie.
