  12.  * This program Calculates the amount of interest in dollars a user earned by 
  13.  * prompting the user to enter the following info: Initial balance 
  14.  * dollars(principal), Interest rate as decibal(rate), and the frequency the
  15.  * interest is compounded annually(T)
  16.  * 
  17.  * Computation is based on the formula: (principal * pow((1+rate/T),T)) - principal
  18.  * ____________________________________________________________________________
  19.  * INPUT
  20.  *	What was your initial balance?:__
  21.  *	What is your interest rate as a decibal value?:__
  22.  *	How many times is interest compounded per year?:__
