Function Pointer (the TOPIC that I missed!) - Part 1

 #include <iostream>

using namespace std;

// Function declaration + definition (function to be pointed to..)

void greet() {

    cout << "Hello!\n";

}

int main() {

    

    // Function pointer

    void (*fp)();

    // Assign the address of greet() fnx to the fnx pointer..

    

    fp = greet;

    

    greet();

    

    return 0;

}

OR

with parameters 

#include <iostream>

using namespace std;

int add(int a, int b) {

    return a+b;

}

int main() {

    // Declare function pointer

    int (*operation)(int, int);

    

    

    // Assign fnx address

    operation = add;

    

    // Call the fnx using pointer

    cout << operation(4, 4);

    return 0;

}
