Lesson 3: Comments

The Introduction: Comments

Comments are very simple yet very useful. A comment is a note you make to the programmer (most often yourself) within a script that does not affect how the program compiles. It takes on two forms, the single-line comment, and the multiple-line comment:

//This is a single-line comment

/*This, however is not.

This is a multiple-line comment*/

The Code: Comments

#include <iostream>

using namespace std;

int main()

{ //Brackets act as a nice container

cout<<"Hello World!";

cin.get();

/*Without cin.get(); our program would

close without giving us a chance to see it.*/

return 0;

}
