C++ LANGUAGE COMMENTS STATEMENTS

C ++ LANGUAGE COMMENTS STATEMENTS 

Program comments are explanatory statements that you can include in 
the C++ code. These comments help anyone reading the source code. 
All programming languages allow for some form of comments. 
C++ supports single-line and multi-line comments. All characters 
available inside any comment are ignored by C++ compiler. 
C++ comments start with /* and end with */. For example: 

/* This is a comment */ 
 
/* C++ comments can also 
 * span multiple lines 
 */ 
A comment can also start with //, extending to the end of the line. For example: 


#include <iostream> 
using namespace std; 
 
main() 
{ 
   cout << "Hello World"; // prints Hello World 
 
   return 0; 
} 


When the above code is compiled, it will ignore 
// prints Hello World and final executable will produce 
the following result: 
Hello World 
Within a /* and */ comment, // characters have no special meaning. 
Within a // comment, /* and */ have no special meaning. Thus, you 
can "nest" one kind of comment within the other kind. For example: 

/* Comment out printing of Hello World: 
 
4. COMMENTS IN C++ 

cout << "Hello World"; // prints Hello World
