C Programming Language: Understanding Comments

Comments are an essential part of any programming language. They allow developers to document their code, provide explanations and additional information, and make it easier for others to understand. In C programming, there are two types of comments: single-line comments and multi-line comments.

Single-Line Comments

Single-line comments start with the "//" symbol and continue until the end of the line. They are used to provide a brief explanation of the code or to temporarily disable a line of code. For example, "// this is a single-line comment" is a single-line comment.

1// this is a single-line comment

Multi-Line Comments

Multi-line comments start with the /* symbol and end with the */ symbol. They are used to provide detailed explanations and can span multiple lines. For example, / this is a multi-line comment that spans multiple lines **/ is a multi-line comment.

1/*
2this is a multi-line comment
3that spans multiple lines
4*/

It is good practice to use comments in your code, as they make it easier for others (and yourself) to understand what the code is doing. However, it is important not to overuse comments, as they can make the code difficult to read and slow down the program.
