function pointer

A function pointer is like a variable that stores the address of a function, allowing your program to decide which function to call dynamically. Instead of directly invoking a specific function, you can assign the address of different functions to this pointer and invoke them as needed. This provides flexibility, such as switching behaviors at runtime or implementing callback mechanisms. Think of it as a bookmark pointing to various callable routines, enabling your code to be more adaptable and modular by passing functions around like data.
