3.10 Summary

I l @ ve RuBoard

A program should be concise and easy to read. It must serve as a set of computer instructions, but also as a reference work describing the algorithms and data used inside it. Everything should be documented with comments. Comments serve two purposes: they describe your program to any maintenance programmer who has to fix it, and they help you remember what you did.

Class discussion 1: Create a style sheet for class assignments. Discuss what comments should go into the programs and why.

Class discussion 2: Analyze the style of an existing program. Is the program written in a manner that is clear and easy to understand? What can be done to improve the style of the program?
