C++ Comments

The Comments are the explanatory statements that we can use in the C++ code. The comments are helpful in reading the source code of the program. The comments are ignored by the C++ compiler because there is no need of comments about the program compiling/execution. Types of comments There are two types of comments supported by C++;

Single-line comments
Multi-line comments.

Difference Between Single Line and Multi Line Comments in C++

Single-line comments A comment can also start with //, extending to the end of the line. For example –

#include <iostream>
using namespace std;
main() {
cout << "I love C++";
// It will print welcome to t4tutorials.com
return 0;
}

#include <iostream>

using namespace std;

main() {

cout << "I love C++";

// It will print welcome to t4tutorials.com

return 0;

}

Multi-line comments C++ comments start with /* and end with */. For example − /* C++ comments can occupy More than one line of comments */

#include <iostream>
using namespace std;
main() {
cout << "I Love C++";
/* C++ comments can occupy

More than one line of comments
*/
return 0;
}

#include <iostream>

using namespace std;

main() {

cout << "I Love C++";

/* C++ comments can occupy

More than one line of comments

return 0;

}
