[C++] Hello World [Code/Tut]

Code:

#include <iostream.h>

 int main()
 {
    cout << "Hello World!\n";
        return 0;
 }

Include <iostream.h>

That is basically tells the compiler what to use sorta

int main()

basically telling the compiler here is where the code begins

cout << "Hello World!\n";

cout << is what you use to write something on the screen.
\n Is what the compiler interprets as new line. Always end with a semicolon out side the Quotation marks

return 0;

All ANSI-compliant programs declare main() to return an int. This value is "returned" to the operating system when your program completes. Some programmers signal an error by returning the value 1
