Comments in C language are used to provide information about lines of code and are widely used for code documentation. There are two types of comments in C language.
Single-line Comments
They are indicated by double slashes (//). Let’s look at an example of a single-line comment in C language.
#include<stdio.h>int main(){// Print information
printf("Hello C");return 0;}
You can even add comments after statements. For example:
printf("Hello C");// Print information

Multi-line Comments
Multi-line comments are indicated by slash and asterisk (/* … */). They can span multiple lines of code but cannot be nested. The syntax is as follows:
/* Code to be commented */
Let’s look at an example of a multi-line comment in C language.
#include<stdio.h>int main(){/* Print information multi-line comment */
