Function Pointers A funtcion pointer stores the memory address of the entry point of a function. This allows functions to be passed as arguments or stored in data structures for dynamic execution. int multiply(int a, int b) { return a * b; } int main() { // Declaration: return_type (*pointer_name)(parameter_types) int (*op_ptr)(int ...

Class Structure in C Implementing object-oriented concepts in C requires a structured approach using structs and function pointers. A class consists of two primary components: Instance Type: A struct containing data members (instance variables) and function pointers (instance methods). Variables of this type are called instances. Class Object ...
