Program 
Documentation
 
 
        Documentation consists of written descriptions about the program. Documentation is needed so that others can understand the program.
 
The user may need to know what the program does and how to use it. The programmers may need to know how to modify the program so as to remove obscure program bugs that are not detected during testing. Modification may also be required to improve the program performance in the future. An example of such documentation is a technical anual which should include:
1)  Title
2)  Specifications of the problem
3)  Data structures
4)  Algorithms
5)  List and definitions of variables used
6)  List of files used
7)  Annotated program listing
8)  Test data
9)  Sample output
 
 
It should be noted that documentation is not something done just at the end of the program development process. It should be done throughout all phases so that important details are not missing. For example, all materials related to the payroll problem presented in this chapter may constitute the final version of the documentation required.
