VC and SDL compilation of flight shooting games

I got up early in the morning and didn't go to class. I felt boring. It was also a bio-chemistry class. I was so tired that I could just enrich my life, it took a day to Use SDL to write a flying shooting game, which should have been played by everyone.

There is nothing to say, It is boundary judgment, and the code is somewhat lengthy. Don't laugh.

I have been working on SDL recently and found that SDL is really a good thing to write graphics, so I have the opportunity to take a deeper look. (I only use the tip of the iceberg)

If you have any shortcomings in this article, I hope you can correct them more.
