I do not know what shold i want to write in that programing and what are the function and does it works

Question

plz do something

Answer 1

You said "in that programing", what did you mean by that ?

Answer 2

You have already started with the tutorial. For now, I would say, just go on with it, and try out yourself what they teach you.

For example after you learned how to put text on the screen, play around with that for a while.

As you go, ideas will come!
