In my calculator seems to be a problem with the input or do I need an extra interpreter

Question

I have to enter all the input at the beginning and not when it is " called". I installed ruby on my Laptop and entered the code in a txt file. Then I ran this file with the interpreter. There it partially worked

Answer 1

For console apps, Code Playground requires all input to be fed to the compiler/interpreter prior to code compilation/interpretation.

Answer 2

No, in the Code Playground it will always be a console app.
