No, but also skip malloc/free until late in the year, and when it comes to heap allocation then don't use example code which allocates and frees single structs, instead introduce concepts like arena allocators to bundle many items with the same max lifetime, pool allocators with generation-counted slots and other memory managements strategies.

Is there any C tutorials you know that do that so I can try to learn how to do it?

Shameless plug ;)

This only covers one aspect though (pools indexed by 'generation-counted-index-handles' to solve temporal memory safety - e.g. a runtime solution for use-after-free).
