/**
 * Name: Bill Mao
 *
 * Date: 11/22/17
 *
 * School: East Chapel Hill High School
 *
 * Program: Program 500a (Mr. Ascii)
 *
 * Description: This program is designed to print out a two column table of ascii characters from 32 to 122.
 * The program first initializes the variable that represents the ascii characters.
 * A loop then executes that increments the variable to even integer values of 32-120.
 * For each value, the ascii character that corresponds to the integer and the ascii character that is one greater are printed.
 * Once all the characters that correspond with those values are printed, the last character (z) is then manually printed...
 * since it does not fit in the two column format.
 *
 * Difficulties: I originally was unsure of how to format the lines of ascii values, but I settled on tabs as they would be the easiest to type out and use.
 * I also had some trouble including z in the two column table.
 *
 * What I Learned: I got more practice with the char primitive data type and loops in Java.
