Question

This assignment worth 10% of your total course grade. Write spim program and execute it on
mars. Your program reads two integer values x, y. Both x and y must be single digit number > 0.
If the user does not enter a value that meets this condition ask the user to enter a new value
again. Also Write two functions. The first function call it SumEven that gets x and y passed as
parameters and returns the sum of even values between x and 10*y inclusive. Also write
another function call it Factorial that gets |y-x| (absolute value of y-x) as a parameter and
returns the factorial of this value. Before you exit your program Must print both values
returned on the screen a long with your name.
Input:
Enter first number: x if x is not single didit ask fox another value
Enter second number y if y is not single digit ask for another value
Output:
Your Name
The value returned by SumEven
The value returned by Factorial.
