Chapter 20, Problem 20.23PE

Evaluate expression Modify Listing 20.12, EvaluateExpression.java to add operators ^ for exponent and % for remainder. For example, 3 ^ 2 is 9 and 3 % 2 is 1. The ^ operator has the highest precedence and the % operator has the same precedence as the * and / operators. Your program should prompt the user to enter an expression. Here is a sample run of the program:

Enter an expression: (5 * 2 ^ 3 + 2 * 3 % 2) * 4

(5 * 2 ^ 3 + 2 * 3 % 2) * 4 = 160
