/**
 * 8.37 (Guess the capitals) Write a program that repeatedly
 * prompts the user to enter a capital for a state. Upon
 * receiving the user input, the program reports whether
 * the answer is correct. Assume that 50 states and their
 * capitals are stored in a two-dimensional array, as shown
 * in Figure 8.10. The program prompts the user to answer all
 * states� capitals and displays the total correct count.
 * The user�s answer is not case-sensitive.
