Comment in C++

Comments can be used to explain C++ code and Comments are portions of the code ignored by the compiler which allow the user to make simple notes in the relevant areas of the source code.

We can use comment in many type in a program for ex:- we can explain the program by single line comment , we can declare the function() work in a program and etc.

Types of comment:-

In a C++/C comments are two types:-

1.    Single line comment

2.    Multiple line comment

Single line comment:-

 Singe line comment start with // and continue until the end of the line. If the last character in a comment line is a \ the comment will continue in the next line.

#include <iostream.h> #include <conio.h>   Void main() {   Cout<<”this is a simple program”;    // comment here    }

 

 Multiple line comment:-

Multiple line comment start with /* and end with */

#include <iostream.h> #include <conio.h>   Void main() {   Cout<<”this is a simple program”;     /* this Is multiple Line comment  */   }
