Reusing Base Initialization

#include <iostream>
using namespace std;

// TODO 1: Create BaseDriver class
//         - Add function initBase()
//         - Prints base initialization messages

// TODO 2: Create SpiDriver class
//         - Inherits publicly from BaseDriver
//         - Add function initSpi()
//         - Calls initBase()
//         - Prints "SPI driver initialized"

// TODO 3: Create I2cDriver class
//         - Inherits publicly from BaseDriver
//         - Add function initI2c()
//         - Calls initBase()
//         - Prints "I2C driver initialized"

class BaseDriver {
    public:    
        void initBase() {
            cout << "Base driver init start" << endl;
            cout << "Base driver init complete" << endl;
        }

int main() {
    int mode;
    cin >> mode;

    // TODO 4: If mode == 0, create SpiDriver and call initSpi()
    // TODO 5: If mode == 1, create I2cDriver and call initI2c()
    if (mode == 0) {
