I have just made a significant rewrite and improvement to a small C game from a book. The original racing car could only move left or right, couldn't move forward or backward, there was only one truck as the passing vehicle with only one color, which was very monotonous. I added forward and backward movement for the racing car, added another small truck, added mileage display and a menu to choose the game difficulty, made the colors of the passing vehicles colorful, and also made it reflect failure if the racing car crashes into the passing vehicles from the left or right sides. In contrast, the original crash was very single...

I hope everyone has time to play it... If you are good at art, you can also change it into a realistic car model by yourself...

Also, I have prepared an executable program that can run independently, which can be played by double - clicking...

But unfortunately, there is only PC SPEAKER, and there is no music yet.. Can anyone who knows how to add it?

The code is messed up by ubb!

Nice

"The code is messed up by ubb!"

The `void disp_box` has all become italic!

Yeah, I don't know how it happened either. But it's okay. If you're interested, just copy it. Or downloading the uploaded file is more convenient,...

Copying is definitely not possible! Because: The in the code is treated as UBB format and converted. Don't believe it, check it yourself.

Then download the uploaded file...

I want to download, why can't I download?

The game has been uploaded..
Welcome to try out..
