title: My code to determine 3 digit palindrome infinitely asking for number
body: <p>I have to make a code that determines if a three digit number is a palindrome (ie 121 where front to back it is the same,) and for some reason the program is infinitely asking for input. I cannot seem to figure out why. Any help would be appreciated, thanks!</p>
  
  <p>Code:</p>
  
  <pre><code>/* Class:         CS1301
   * Section:       9:30
   * Term:          Fall 2015
   * Name:          Matthew Woolridge
   * Instructor:    Mr. Robert Thorsen
   * Assignment:    3
   * Program:       4
   * ProgramName:   PalindromeNumber
   * Purpose:       To tell the user if a number is palindrome
   * Operation:     The information to be numbers are statically instantiated in the code and
   *                the table is output to the screen.
   * Input(s):      The user inputs a three digit number
   * Output(s):     The output is whether or not the number is palindrome
   * Methodology:   This program will use selections, math statements and print to determine and tell the user if a number is palindrome
