Comments in C or any other programming language is very important. It is never ever helpful for any user but they play a very important role if other programmers wish to understand your programming code.
There are two types of comment syntax in C language. You can use any one of them but as per usages.
Type of Comments in C
There are two types of comments in C language.
- Single line comment
- Multiline comment
Single line comments in C
If you want to use a comment that it is only a single line. So you can use single-line comment syntax.
//single line comment
#include<stdio.h>
#include<conio.h>
void main()
{
int a,b; //variable declaraction
clrscr(); //clear the screen
printf("Hello World");//print the statement "Hello World"
getch();//display output screen until you press any key
}
You can see above code, all statements have single-line comments. You can use comments in your programming code. Commenting in your program code is a good habit. It helps other programmers to understand your code.
Multiline Comments in C
If you want to write a few lines as a comment to understand other programmers about your program code. You can use multiline comments in C.
/*multiline comments that are easy to use in C*/
#include<stdio.h>
#include<conio.h>
/*This program is a simple program that is used to
display a simple message hello world in console*/
void main()
{
int a,b;
clrscr();
printf("Hello World");
getch();
}
In the above code, you can see an example of a multiline comment in C. Basically, it is used to brief the program concepts, variable initialization, and role of a function.
