This article covers the basics, but it only scratches the surface of C programming and all the associated knowledge. A good reference book will help you solve problems and save you from a lot of headaches down the road. There are lots of communities, both online and in the real world, dedicated to programming and all of the languages that entails. Find some like-minded C programmers to swap code and ideas with, and you will soon find yourself learning a lot.  Attend some hack-a-thons if possible. These are events where teams and individuals have time limits to come up with programs and solutions, and often foster a lot of creativity. You can meet a lot of good programmers this way, and hack-a-thons happen regularly across the globe. You don't have to go back to school for a Computer Science degree, but taking a few classes can do wonders for your learning. Nothing beats hands-on help from people who are well-versed in the language. You can often find classes at local community centers and junior colleges, and some universities will allow you to audit their computer science programs without having to enroll. Once you have a grasp of C, it wouldn't hurt to start taking a look at C++. This is the more modern version of C, and allows for a lot more flexibility. C++ is designed with object handling in mind, and knowing C++ can enable you to create powerful programs for virtually any operating system.
