C language writing rules:

1. One description or statement occupies one line .

2. The part enclosed by {} usually represents a certain hierarchical structure of the program. {} is generally aligned with the first letter of the structural statement and occupies a separate line.

3. Statements or explanations at a lower level can be written with a certain number of spaces indented compared to statements or explanations at a higher level. In order to look clearer and increase the readability of the program. You should strive to follow these rules when programming to develop a good programming style.
