// The purpose of this program is to calculate the accumulated
// value of pennies after each day, if we were to be given one 
// penny to start the first day, and double each previous day 
// thereafter for a certain number of days specified by the user.
// We would also like to know after how many days will we make at
// least $1,000,000.  
//
// Table of Variables:
// -------------------
// days       =  number of days the user wants to 
//               calculate accumulation of pennies for
// dday       =  the day you will have at least $1,000,000
// added      =  number of pennies added each day
// total      =  total number of pennies added so far
// sum        =  total value of pennies added so far
//
