                        Program #1 Output

1) #include <iostream.h>

2) int main(){

3)      cout<<"Hello World\n";

4)      return 0;

5)  } 

--------------------------------------------------------------------------------------

This tutorial will explian each line of code in a short but understandable manner.

Line 1: This line is called the include directive it is save on your hard drive as iostream.h. It tells the compiler that you will be accessing it for your program.

Line 2: For now what you should konw is - int main ()  is  the area of  the program  that is actually visible to the user.

Line 3: cout is a command we use from the directive in line 1. To print text to the screen a pair of double qoutes are use, with the actual text is in between the qoutes. the \n tells the computer to print a new line.

Line 4: This line is used by the compiler to check if the program ran successfully.

Line 5: Simply closes the { we had in line 1. The text between the {} is called the body.
