How do I create a tic tac toe?

You need to first figure out how to draw the grid, because you will be using it over and over.

Then you need to work on the data entry interface:
– which is X, and which is O
– not overwriting a filled space

Then there is row detecting – how will the code determine if there are three in a row? Up, down, and diagonal.

Probably use a 2-dimensional array to track what blocks are filled (and with what), and then some sort of a comparator set to decide if you have a winner.

Now – do the work.

Learning programming involves a lot of trial and error (and also maybe some reading). When what you have tried doesn’t work, look at what it DID do, and try to understand why it might have done that. Make changes to your code to try to get it to do it a bit differently, see what THAT does, and repeat until you understand why it does what it does. Once you understand enough of how it works, you’ll be able to do whatever you want it to do . . . until you’re surprised again, and then you go back to trial and error (and/or reading) on that part.

It was the code for me that has always been some kind of dull work that I put off everything, so I liked to use ready-made constructors and write off the code from there, modifying it a little :)
