This textbook has been prepared with the aim of teaching C programming by example. Therefore, it is rich in examples that are explained in some detail. It is intended that you try writing the examples that are contained in the text and to compile these and run the executable files in order to ensure that you confirm to yourself that the explanation that is offered is supported by program execution.
The examples that we have given here are designed to work with C compilers. It is acknowledged that many C++ compilers will compile the code but errors and warnings will result. If you intend using these compilers, you will need to change the syntax accordingly. However, the structure of the programs will not need to be changed and they will produce the desired result when compiled.
