Introduction
If you want to be proficient in the writing of code in the C programming language, you must have a thorough working knowledge of how to use pointers. Unfortunately, C pointers appear to represent a stumbling block to newcomers, particularly those coming from other computer languages such as Fortran, Pascal or Basic.
To aid those newcomers in the understanding of pointers I have written the following material. To get the maximum benefit from this material, I feel it is important that the user be able to run the code in the various listings contained in the article. I have attempted, therefore, to keep all code ANSI compliant so that it will work with any ANSI compliant compiler. I have also tried to carefully block the code within the text. That way, with the help of an ASCII text editor, you can copy a given block of code to a new file and compile it on your system. I recommend that readers do this as it will help in understanding the material.
