part 2:
is to convert a person height in feet and inches to meter
for example
What is your name? Steve
What is your height?
Feet: 6
Inches: 4
Steve, your height in meters is 1.93
To convert the height to meters, you must first convert height from feet and inches to just inches. Then you can convert the inches to meters. Since there are 12 inches in a foot, 2.54 inches in a centimeter, and 100 centimeters in a meter, you can use one equation to do all the conversion:
Hm = ((Hf * 12) + Hi) * 2.54 / 100
where Hf is the number of feet entered by the user Hi is the number of inches entered by the user Hm is the height of the person in meters In the above example, Hf = 6, Hi = 4, and Hm = 1.93
