i have to make a code that will create, draw, ask the user to add new values, and sort the array by making a menu to help choose which part to do.

Ok, so again, what is your question?

how to get the program to run, bc i dont know how to make it prints the array and i dont know how to add new values into the array?

how to get the program to run

If you don't know how to run the program it is better to do some tutorials before doing this, I think. Isn't it?
