Query: Excellent way to learn C programming!

I needed to learn to program in C for my job. Unfortunately I was unable to find any community college or other in-person type courses that taught C programming. I spent several months struggling trying to learn C through Element K and other online resources. Having previously used the Visual Quickstart series to learn HTML, I finally purchased the C Programming Visual Quickstart Guide. It was the best purchase I have made in a long time! The two column format is FAR easier to follow than the traditional single column approach. The examples teach the content very specifically by highlighting (in bold) the relevant code in the scripts found on the right-hand side of the page. I am learning to program in C quickly and easily. I wish I had bought the book in the first place!
