How to modify local static variables with static in C language

Today, I would like to share with you the relevant knowledge of how to modify local static variables with static in c language. The content is detailed and the logic is clear. I believe most people still know too much about this knowledge, so share this article for your reference. I hope you can get something after reading this article. Let's take a look at it.
