Guidelines on Structure:
When you wrote programs, i will give you some most experience tips that can be easily read and debugged by you (when you come back to it later) and others (who may have to change your program later).
- A well-structured program should indent all instructions inside each block (i.e. following an opening curly brace – { ). Therefore, inside a block another block will be indented two times etc. This helps to show which instructions will be run into the program , and also helps to line up opening and will be closing into curly braces.
- So that it is often helpful to different stages of a program by putting an extra blank line (and maybe a comment explaining what the next stage does) between each stage.
- Another good experience or better way that helps the inside readability each instruction is to put spaces after commas when listing parameters (i.e. data) to be given to a function. This recognizes where every parameter starts and makes the program simpler to peruse. Spaces before and after brackets, assignments (=) and operators (+ – * / < > == != etc.) can also help make things more readable – but this is up to you.
- Start a program with a /* comment */ that explains the purpose of the program, and who wrote it. This is useful in case you ever have to work on somebody else’s program, and you need to ask them for advice on how it works.
- If you will create a new function in the program , put then you will put a comment before it showing what data goes in, and what comes out, and the purpose of the function.
- If a part of your code is quite difficult to follow, or you should to explain why you have written this way , or regardless of whether you wish to state that it could be improved (and how) yet you haven’t an opportunity to improve yet, at that point utilize a remark.
