Reusing Base Initialization

#include <iostream>
using namespace std;

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

        cout << "Base driver init start\n";
        cout << "Base driver init complete\n";

};

class SpiDriver : public BaseDriver{
public:
    void initSpi(){
        cout << "SPI driver initialized\n"; 
    }
};

class I2cDriver : public BaseDriver{
public:
    void initI2c(){
        cout << "I2C driver initialized\n"; 
    }
};
// 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

    case 0: {
