Constructor Order Inheritance

#include <iostream>
using namespace std;

// TODO 1: Create a base driver class with a constructor
//         that prints "Base driver initialized"
class Base{
    public:
    Base(){
        printf("Base driver initialized\n");
    }
};
// TODO 2: Create a derived driver class that inherits from the base driver
//         - Constructor takes an int value
//         - Prints "Derived driver initialized"
//         - Stores the value
//         - Has a function to print "Driver value <value>"
class Derived : public Base{
    int value;
    public:
    Derived(int v) : value(v){
        printf("Derived driver initialized\n");
    }
    void print(){
        printf("Driver value %d\n",value);
    }
};
int main() {
    int value;
    cin >> value;

    // TODO 3: Create a derived driver object using value
    Derived d(value);
    // TODO 4: Call function to print the value
    d.print();
    return 0;
}
