Constructor Order Inheritance

#include <iostream>
using namespace std;

// TODO 1: Create a base driver class with a constructor
//         that prints "Base driver initialized"
class BaseDriver {
public:
    BaseDriver() {
        cout << "Base driver initialized" << endl;
    }
};
// 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 DerivedDriver : public BaseDriver {
public:
    DerivedDriver(int v) : value(v) {
        cout << "Derived driver initialized" << endl;
    }

    void printValue() {
        cout << "Driver value " << value << endl;
    }

private:
    int value;
};
int main() {
    int value;
    cin >> value;

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