int main()
{
   puts("I love displaying text!");
   return(0);
}

Output

I love displaying text!

Notes

* A long time ago, when computers were controlled primarily by the command prompt, I wrote a program like this. It displayed the text "Who's there?" The name of the program was Knock-Knock.

* Incidentally, you don't need to save updates as separate projects or source code files. If the book asks you to modify or update a previous Exercise, just keep working with the original file. It's easier.
