Function Pointers and Callback Architectures

Declare, assign, and invoke function pointers with various signatures.

Use `typedef` to simplify function pointer declarations and improve code readability.

Implement a callback mechanism by passing function pointers as arguments to other functions.

Design a dispatch table using an array of function pointers to replace `if-else` or `switch` chains for command processing.

Analyze the use of function pointers for notification and callback patterns in an AUTOSAR-style architecture.
