Project 4 DUE: 7 Dec

Requirements Specfication

Write a program that will figure out how old you will be when your age is 75 percent of your mother's age. (If you prefer, you can use your father's age.) For this project, use integers and instead of testing for equality (==), test for greater than or equal. Otherwise, you might end up in an endless loop. You calculate the percentage by dividing your age by your parent's age.

Since you are not at that percentage now, you will have to keep trying ages until you get there, so use a loop and keep adding one to both ages until you get to the goal.

You must make sure that all ages are greater than zero, that all ages are less than some value (maybe 150 or something reasonable), and that the parent is older than the child. If the ages are not valid, then make the user re-enter the ages.

You must use at least these functions for the following:

Example Input/Output

In the following example, the program displays what is in Blue. The user's input is in red. 

What is your age? 20
What is yor parent's age:  40
When you are 60, you will be 75% of your parent's age.

Grading

This project will be grade using the following scale:

Documentation 25 points
Correct Results25 points
Correct Sytle25 points
Other25 points

You will lose 5 points if you do not name the file correctly.
You will lose 5 points if you email the project instead of submitting it via Blackboard.
You will lose 5 points if the prompt is not on the next line.
You will lose 5 points if you have less than four functions (not counting main).
