Chapter 5, Problem 8P

(You need to do Practice Programs 4 and 7 before doing this one.) Write a program that combines the functions of Practice Programs 4 and 7. The program asks the user if he or she wants to convert lengths or weights. If the user chooses lengths, then the program asks the user if he or she wants to convert from feet and inches to meters and centimeters or from meters and centimeters to feet and inches. If the user chooses weights, a similar question about pounds, ounces, kilograms, and grams is asked. The program then performs the desired conversion. Have the user respond by typing the integer 1 for one type of conversion and 2 for the other. The program reads the user’s answer and then executes an if-else Statement. Each branch of the if-else Statement will be a function call. The two functions called in the if-else statement will have function definitions that are very similar to the programs for Practice Programs 4 and 7. Thus, these functions will be function definitions that call other functions in their function bodies; however, they will be very easy to write by adapting the programs you wrote for Practice Programs 4 and 7.

 Notice that your program will have if-else Statements embedded inside of if-else statements, but only in an indirect way. The outer if-else statement will include two function calls as its two branches. These two function calls will each in turn include an if-else statement, but you need not think about that. They are just function calls and the details are in a black box that you create when you define these functions. If you try to create a four-way branch, you are probably on the wrong track. You should only need to think about two-way branches (even though the entire program does ultimately branch into four cases). Include a loop that lets the user repeat this computation for new input values until the user says he or she wants to end the program.
