Write a program that will include the 6 functions outlined in textbook Ignore the output in the text book along with the example program included in the textbook files. Your program will result in the output shown below.

See the attached 7A_Hints file attached above for a list of functions and brief description of each function.

Create function definitions at the top of your program and the functions below your main method.

Next implement one function at a time. Compile your program and make sure the output matches what is requested. Then move to the next function.

Most functions require if statements. Many if statements can just return a value if true and therefore the rest of the function does not need to execute.

If you get the warning: "Not all control paths return a value." that means that you must use either a final else return value or simple return value at the end of your function as shown above.
