bool MoreData() This function asks the user if there is more data to be input. The function returns true when the user responds in the affirmative by inputting uppercase or lowercase y, and false when the user responds in the negative by inputting uppercase or lowercase n. If the user inputs a value other than y or n, then the function should reprompt the user to enter a valid value.

double Power (double, int) This function returns the value computed by raising the value indicated by the first parameter (the base) to the power indicated by the second parameter (the exponent). The function should allow negative, positive, and zero-valued (integer) exponent values. For example, Power(2.5, 3) should return the value 15.625, which is (2.5)³, and Power(2.0, -2) should return the value 0.25, which is (2.0)^-2.
