Question

C++ Programa that:

// 1) Ask the user to enter two numbers greater than zero. Store the

//    values into two variables named 'n' and 'm'.

//    Additionally, implement a while-loop to keep asking the user to enter

//    the numbers again if any of the two numbers are equal or smaller than zero.

// 2) If the two numbers (n, m) are equal, display the message "The

//    numbers are the same". If the two numbers are different, display

//    the message "The numbers are not the same".

// 3) Calculate and display the number n elevated into the power of m: n^m

//    Store the result into a variable named 'X'.

//    HINT: Use the pow() function.

//    EXAMPLE: If n = 3 and m = 2 then X = 3^2 = 3 * 3 = 9

//    EXAMPLE: If n = 2 and m = 3 then X = 2^3 = 2 * 2 * 2 = 8

//    EXAMPLE: If n = 5 and m = 1 then X = 5^1 = 5

//    EXAMPLE: If n = 1 and m = 3 then X = 1^3 = 1 * 1 * 1 = 1

// 4) The result from (c) is already stored into the variable 'X'.

//      Calculate and display the factorial for the value in 'X': X!

//    Store the result into a variable named 'factorial'.

//    HINT: Use a for-loop similar to the for-loop used to calculate the

//          mean of a sequence of numbers in the file 5.3-For.cpp. Instead

//          of adding numbers, now we want to multiply numbers.

//    EXAMPLE: If X = 9, then factorial = 9! = 1 * 2 * 3 * 4 * 5 * 6 * 7 * 8 * 9 = 362880

//    EXAMPLE: If X = 8, then factorial = 8! = 1 * 2 * 3 * 4 * 5 * 6 * 7 * 8 = 40320

//    EXAMPLE: If X = 5, then factorial = 5! = 1 * 2 * 3 * 4 * 5 = 120

//    EXAMPLE: If X = 1, then factorial = 1! = 1

//    NOTE: The calculation of a factorial can result in a really a big number,

//          and the compiler may give an incorrect result. Use the numbers

//          provided in the examples to test your code.

// 5) Add code to ask the user if he wants to quit the program. If

//    the user enter 'yes' the program exits, if the user enter 'no' or any

//    other string, the program will execute again.
