C++ Comments

Comments can be used to explain C++ code, and to make it more readable. It can also be used to prevent execution when testing alternative code. Comments can be singled-lined or multi-lined.

Single-line comments start with two forward slashes (//).

Any text between //  and the end of the line is ignored by the compiler (will not be executed).

Fig: C++ Comments

Single line Program:

#include <iostream>

using namespace std;

int main() {

  // This is single line comment

  cout << "Hello World!";

  return 0;

}

Output:

Hello World

 

Multi-line comments start with  /* and ends with */.

Any text between  /* and */ will be ignored by the compiler:

 

Multi-Line program:

#include <iostream>

using namespace std;

int main() {

  /* this is multi-line comments and print

 hello world */ 

  cout << "Hello World";

  return 0;

}

Output:

Hello World
