Here's a list of mildly interesting things about the C language that I learned mostly by consuming Clang's ASTs. Although surprises are getting sparser, I might continue to update this document over time.

There are many more mildly interesting features of C++, but the language is literally known for being weird, whereas C is usually considered smaller and simpler, so this is (almost) only about C.

struct foo {
   struct bar {
 int x;

What is scope?

Scope determines whether variables can or can't be accessed in different places in your code. Globally scoped variables can be accessed anywhere in your code. When a variable is declared outside of a function it is globally scoped. Global scope can span across different files. Variables defined inside functions are locally scoped, meaning they can only be accessed within that function. This means that variable names can have the same name as long as they are defined in different fuctions. You can define a variable with the same name as a global variable inside of a function and it will be seperate from the global variable.

Why are global variables avoided?

We avoid global variables because they can cause unintended side effects. This can lead to code that is difficult to debug.
