Advanced C: Pointers, Memory, and Aliasing

Compare pointer arithmetic behavior across typed, void, and function pointers, identifying standard compliance and undefined behavior.

Implement a state machine using a function pointer array (jump table) and compare its performance against a switch-based implementation.

Implement a callback-driven event handler for event-driven embedded programming.

Explain heap allocator internals, including the roles of sbrk/brk, free lists, coalescing, and fragmentation.

Implement a fixed-block memory pool allocator for deterministic memory management in real-time systems.

Identify and fix dangling pointer, wild pointer, double-free, and memory leak bugs in C code samples.

Explain pointer aliasing problems and apply the `restrict` keyword to enable compiler optimizations in performance-critical code.

Apply strict aliasing rules and implement safe type-punning using unions or memcpy.
