Some good programming styles that every programmer should follow

Whether you are an amateur or a professional programmer, correct programming style will not only help improve the functionality of software products, but also significantly reduce the occurrence of software disasters. Today, we’ll look at some of the best rules that can help us achieve a better programming style.

Code readability is paramount

For code to be readable and understandable, it needs to be formatted in a consistent way. The names of functions and variables should be meaningful, and the expression of comments should be concise and accurate. Also, it's important to accurately document all the tricky parts of your code. You must understand why a software program works and why it works smoothly under all possible circumstances.

Following correct naming conventions is a must

When it comes to naming classes, functions and variables, you need to follow the following guidelines:

Make sure the first letter of a specific class name is capitalized;

Use uppercase and lowercase to separate multiple Naming of words;

Capitalize constant names and use underscores to separate words;

Make sure the first letter of specific function and variable names is lowercase;

Be careful to use abbreviations correctly. For example, use max instead of maximum.

Use spaces when necessary

Although spaces are meaningless to the compiler, they can be used to improve the readability of the code. For example, you can leave three blank lines between functions. You can also use separate blank lines within functions to separate critical sections of code.

Ensure that the code has a certain maintainability

We need to ensure that the written code is clear and easy to understand if it is replaced by another programmer to adjust functions and fix bugs. Key values ​​in the function should be marked with constants, so that we can change these constant values ​​at any time as needed. All in all, the code must be robust, able to handle any type of input, and then provide the expected results without crashing.

Comments must be easy to understand

Comments should be meaningful and clearly explain everything about the software program. The number of comments does not matter, the quality is the key. You need to write comments using the /*comment*/ style, ensuring they are at the top of each source file. Additionally, you can choose to include your name in the comment, the date the code was written, and a concise description of what the program actually does. However, you can choose to omit some comments that have obvious functionality. The inline comment format you need to follow is //comment.

Use functions correctly

The code snippets contained in each function must be short and able to complete a specific task. Think of functions as "black boxes" - independent yet capable of efficiently processing any type of input. Don't forget such a rule of thumb - the so-called "Ten Line Rule", that is to say, if a function, generally speaking, exceeds 10 lines, it needs to be simplified in the most refined way. Also, any repetitive code snippets should be set up as a separate function. The above approach can not only shorten the length of the program, but also greatly improve its readability.

Neat code indentation

Indentation plays a vital role in the flow control of software programs. Every new while, for, if statement, and switch structure requires indented code. This can also be used when the parentheses have been omitted from a statement in a line. For example, if there is an if statement, then the corresponding else statements must be indented together.

Conclusion

If you are familiar with these correct programming styles, writing software programs will become a very interesting activity. Finally, I hope this article can be of benefit to you.
