Thanks for the clear explantion of your assignment.
Now what do you want us to help you with?

What have you done so far?

Do you know how to prompt for and read a string from the user?

Do you know how o convert an input string to a number?

Do you know how to add two numbers and store the result?

Do you know how to detect an empty string?

If you know all of the above you know how to solve the problem.

If not tell us what part you don't know.
