A1. Use of white space to visually split different logical blocks of code. - This greatly improves readability for future programmers.
Comments in code to explain what the code does. - This makes understanding the code simpler for future maintenance programmers.
- Comments should also be added to indicate when and who made changes.
Indent statements within control structures to visually separate them from the control structure statements.- This greatly simplifies understanding of the source code as programmers can see the overall logic at a glance.
Always using standard sequence, selection and iteration control structures. - This makes the code much easier to follow and understand.
- If unconditional jumps and other non-standard structures are used then following the logic becomes difficult.
- Standard control structures allow maintenance programmers to more easily comprehend the logic.
Each subroutine should solve a single well defined problem within the larger problem. - When modifying and testing a program it is much easier to comprehend the processing when a single well defined task is accomplished within each subroutine.
