Print this homework sheet, bring it to the class, and turn it in right
before the next lecture starts.
- (100 pts) Write a program that reads in two lengths in the format
x' y'' (i.e. x feet y inches) and returns the difference in
length between the two in the same format. You may assume that the first
is always larger than the second!
A typical run of your program should look like this (user input shown in
red):
Enter two lengths in feet and inches (larger first!)
32' 6''
15' 11''
Difference is 16' 7''
Turn In a printout of your source code, a screen capture of your
program running on the above example input and a printout of this page
with name, alpha, help-info filled in. These should be stapled together.
- Hint 1: First work on getting your program simply
read the four
measurement values, then work on getting it to print out the
difference in inches, then work on getting the difference in
feet and inches.
- Hint 2: The string constant
"'"
works just fine, but to get the character constant of the
apostrophe you must write '\'', which uses the
backslash as an escape character.
- Hint 3: For ideas on how to chop a length in inches
into feet and inches, look at the
Minutes and Seconds
program, which has to deal with the similar problem of
chopping a time in seconds up into minutes and seconds.
