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\n";
        cout << "Base driver init complete\n";
    }
};
// 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\n";
    }
};
// 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==0) {
        SpiDriver spid;
        spid.initSpi();
    }
    // TODO 5: If mode == 1, create I2cDriver and call initI2c()
    if (mode==1) {
        I2cDriver i2cd;
        i2cd.initI2c();
    }
    return 0;
