Random number generator C Language

I have read 90% of the mathematical analysis, but I have not studied it in depth. This code is copied, and the core part is copied. It feels good.

Generate a fixed random number sequence, as long as the seeds are the same. This random number generator is transparent and easy to change. It is good.

Every time you implement the code, you will find a lot of problems. And, once you write the code, time will fly... very good.

Okay, post it. I'm here for an Internet cafe, and I'm writing a blog while playing a movie. Haha. It's good.
