/******************************************************************************
Write a program that prints the following line of output 1000 times:
All work and no play makes Jack a dull boy.
You should not write a program that uses 1000 lines of source code; 
use methods to shorten the program. 
What is the shortest program you can write that will produce the 1000 lines of output,
using only the material from this chapter?
