Query: Hard to follow.

The authors give examples of concepts by creating a function. However, the function is not used in a simple program. I was able to create programs that used the authors function up to about Chapter 8. There are examples at the end of the chapters, but they are very complex and it is hard to match the function example with the end of chapter example.Expecting a beginning programmer to write the program-driver is a two edged sword.The writing of a driver is good experience, but I hit a wall at Chapter 8.This book was part of course at an online unversity. So, most of the learning is on my own. So, now I am deciding if I should withdraw and take a hit on the pocketbook and transcript or buy additional, better rated books on Amazon.
