When calling a function with a parameter, would you need to specify the parameter as well or just () ? Thank You.

Sorry if the question seems trivial, I was just curious if you need to specify the parameter when calling a function with a parameter or is function name plus open and close parentheses enough?

I am not sure if i understand you correctly, but:

If you call a function which needs a parameter, you of course have to give the function the parameter it need to work. Example: println() --> if you don't give the function a parameter it won't print anything to the console.

You just use function calls with open and close parentheses if the function does not require any parameters.
