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<<"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"

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

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