NSLog (@"Programming is fun.");

Program 13.3. Output

* * *

Programming is fun.

Program 13.3 consists of two functions: printMessage and main. As mentioned earlier, the idea of calling a function is not new. Because printMessage takes no arguments, you call it simply by listing its name followed by a pair of open and close parentheses.
