C comments

In C programming, comments are used to annotate code, making it easier to understand and maintain. They are ignored by the compiler during the compilation process. There are two types of comments in C:

1. Single-line Comments

Single-line comments begin with // and extend to the end of the line. They are useful for brief explanations or notes.

Example:

c
// This is a single-line comment
int a = 5; // Initialize variable a

2. Multi-line Comments

Multi-line comments start with /* and end with */. They can span multiple lines, making them ideal for longer explanations or to temporarily disable sections of code.

Example:

c
/*
This is a multi-line comment.
It can span multiple lines.
*/
int b = 10; /* Initialize variable b */

Best Practices

    Use comments to explain the purpose of complex code sections.
    Avoid excessive commenting; code should be self-explanatory where possible.
    Keep comments up-to-date with code changes to prevent misinformation.

Comments are crucial for improving code readability and collaboration among developers.
