  1. (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.
