Hi

Question

How would you determine the output by the users input

Answer 1

Theo ,

Also add a tag for the language you are working in, since the syntax depends on that.

Answer 2

1. Store the input in a variable.
2. Write the program logic, according to the task.
3. Print the result.

Basically all programs are like that.

Your question is too general for giving a meaningful response... please can you explain more, what your problem is?
