Write a program that calculates and displays values for y when

y = xz / (x-z)

your program should calculate y for values of x ranging between 1 and 5 and values of z ranging between 2 and 6. The x-variable should control the outer loop and be incremented in steps of 1 and z should be incremented in the step of 1. Your program should also display the message function undefined when the x and z values are equal.

(a)- Write a program to reverse the digits of a positive integer number. For example, if the number 8735 is entered, the number displayed should be 5378. (Hint: Use a do statement and continuously strip off and display the units digit of the number.If the variable num initially contains the number entered, the units digit is obtained as (num % 10). After units digit is displayed, dividing the number by 10 sets up the number for the next iteration. Thus, (8735 % 10) is 5 and (8735/10) is 873. The do-statement should continue as long as the remaining number is not zero.

(b)- Run the program written in exercise 2(a) on a computer and verify the program using appropriate test data.
