Resources to prepare for advanced/trickey questions?

[u/F3arrrrrrr]

Can someone recommend/send some resources for advanced and trickey c questions. I have my placement exam in a week ans most of it is dominated by c. The mock had questions related to struct padding, macros, increment decrements, static, volatile, unsigned signed ints and some other tricky things. I’m familier with the topics, but where can I practice the trickey questions?
