Chapter 5, Problem 7P

(You should do the previous two Practice Programs before doing this one.) Write a program that combines the functions of the previous two Practice Programs. The program asks the user if he or she wants to convert from pounds and ounces to kilograms and grams or from kilograms and grams to pounds and ounces. 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 the previous two Practice Programs. Thus, they will be function definitions that call other functions in their function bodies. 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.
