// Muhammad Naveed

// (Separating the Digits in an Integer) Write an application that inputs one number
// consisting of five digits from the user, separates the number into its
// individual digits and prints the digits separated from one another by three
// spaces each. For example, if the user types in the number 42339, the program should print
//              4	2	3	3	9
// Assume that the user enters the correct number of digits. What happens when you
// execute the program and type a number with more than five digits? What happens
// when you execute the program and type a number with fewer than five digits?
// [Hint: It’s possible to do this exercise with the techniques you learned in
// this chapter. You’ll need to use both division and remainder operations to
// “pick off ” each digit.]
