Reusing Base Initialization

#include <iostream>
using namespace std;

// TODO 1: Create BaseDriver class
//         - Add function initBase()
//         - Prints base initialization messages
class BaseDriver{
    public:
        void initBase(){
            cout << "Base driver init start" << endl;
            cout << "Base driver init complete"<< endl;
        }
};

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

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

};

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

class I2cDriver: public BaseDriver{
    public:
        void initI2C(){
            initBase();
        cout << "I2C driver initialized" << endl;
        }
};

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

    // TODO 4: If mode == 0, create SpiDriver and call initSpi()
    if(!mode){
        SpiDriver spi;
        spi.initSpi();
    }
    else{
        I2cDriver i2c;
        i2c.initI2C();
    }



    // TODO 5: If mode == 1, create I2cDriver and call initI2c()

    return 0;
