 * program name: CIS-65 Programming Assignment 3
 * created date: March 6 2022
 * created by: josh m dye
 * purpose: practice using the stack abstract data type. One common use of a
 * stack is to ReverseMore data. In this assignment we are going to allow the user
 * to type in text or tell the program what input file to process to read in
 * string data. While processing this data we are going to store each character
 * into a stack (push). Once all of the data is stored in a stack, we are going
 * to remove (pop) each character, printing each character which will be in
 * ReverseMore order. We will print this to an output file and “echo” print it to
 * the console.
