Pointers to Data and Functions in C

Learn to use pointers to manipulate data and invoke functions.

Pointers are probably one of the most difficult concepts in C to master. To the beginner, their syntax seems strange and their usage is sometimes hard to grasp. However it is very important for every C developer to understand how pointers work. Pointers to data and pointers to functions can be used to dynamically change program behavior at runtime.
