// Directions:  You try compiling and running the program.
// The compiler will stop where it finds the 1st error.
// Read the feed back towards the bottom area of the IDE
// window.  The error message might not always lead to a 
// clear understanding of the problem.
// Look to the comments numbered 1. It will tell you what
// the problem is and how to fix it.  Once fixed, try
// compiling and running the program again.  If it should
// stop again resolve the problem by doing the same steps.
// Do this as many times as needed to resolve all errors.
