You are to write a program utilizing reference parameters. Your program should have
the following four functions: menu, sum, power, gcd.
Your program should first call menu, and display the options for your program – to find
the power of x raised by y; the max power x can be without exceeding y, and printing out
a number backwards. The choice is sent back via reference parameter (so it should be an
argument). Reuse/recycle your menu function from Assignment 8.
Next, your program should prompt for value(s) and then will perform the calculations for
power, maxPower, or backwards (which is just printing out the number in reverse). The
functions power and maxPower have return type int, while backwards has a return type of
void. The power function will have two arguments: the number to raise and the power to
raise the number to; the maxPower function will have two arguments: the number to
raise and the number not to exceed; and backwards has one argument, the number to print
out in reverse.
Your program should print out the result to the screen. Last, your program should ask the
user to select an option from the menu of four choices.
One other note: each of the functions must solve its calculation/output recursively
(see Ch. 6).
Brief descriptions:
Power: the power of x raised by y
Power(3,4) = 3*3*3*3 = 81
maxPower: the power of x raised by ? not to exceed y
maxPower (2, 31) = 4
maxPower(5, 125) = 3
backwards(123456789) prints out 987654321
Sample run:
1) Find the power of x raised by y.
2) Find the maximum power of y that does not exceed x.
3) Print out a number backwards.
4) Quit

Enter the number to raise: 5
Enter the number not to exceed: 624
