C Comments

C comments

Created By: chatGPT

In C, comments are used to explain the code and make it easier to understand. They are completely ignored by the compiler, meaning they do not affect the program's execution. There are two types of comments in C: single-line comments and multi-line comments.

// This is a single-line comment

Single-line comments begin with // and continue until the end of the line. They can be placed on their own line or after a line of code.

int x = 5; // Initialize x with 5

Multi-line comments begin with /* and end with */. These comments can span multiple lines and are useful for longer explanations or temporarily disabling blocks of code.

/*
   This is a multi-line comment.
   It can be used to explain complex logic.
*/

Keep in mind that multi-line comments cannot be nested. If you put a /* inside another /*, it will cause an error when compiling.

/* Comment 1 /* Comment 2 */ Comment 1 ends */

Using comments effectively is a key part of writing clean code. Always aim to make your comments concise and relevant to help other programmers understand your intentions.

// Good practice:
// Function to add two integers
int add(int a, int b) {
    return a + b;
}
