C Multi Line Comments

C multi line comments

Created By: chatGPT

In C programming, multi-line comments are used to include explanations or annotations within the code that might span multiple lines. These comments help other programmers (or yourself) to understand what the code does without affecting its execution. Multi-line comments begin with /* and end with */. Anything written between these symbols will be ignored by the compiler.

/* This is a multi-line comment
   It can span
   multiple lines. */

Using multi-line comments can be particularly helpful when documenting complex logic or providing detailed explanations. However, be cautious not to nest multi-line comments, as this will lead to compilation errors.

/* This is a valid comment
   /* This is an invalid nested comment */
   Thus, it should not be used. */

Here’s an example to demonstrate multi-line comments in action. This sample code calculates the area of a rectangle and includes a multi-line comment to explain its purpose.

/* Program to calculate area of a rectangle */
#include <stdio.h>

int main() {
    int length, width, area;
    /* Input values for length and width */
    printf("Enter length: ");
    scanf("%d", &length);
    printf("Enter width: ");
    scanf("%d", &width);
    area = length * width;
    printf("Area of the rectangle: %d\n", area);
    return 0;
}
