UART Config Class

#include <iostream>
using namespace std;

// Define UartConfig class here
// <write your code>
class UartConfig{
    private:
        int baudrate, parity, stopBits;
    public:
        UartConfig(int baudrate, int parity, int stopBits){
            this->baudrate = baudrate;
            this->parity = parity;
            this->stopBits = stopBits;
        }

        void update(int b, int p, int s){
            this->baudrate = b;
            this->parity = p;
            this->stopBits = s;
        }

        void print() {
        cout << "baud=" << baudrate
             << " parity=" << parity
             << " stop=" << stopBits;

int main() {
    int b1, p1, s1;
    int b2, p2, s2;

    cin >> b1 >> p1 >> s1;
    cin >> b2 >> p2 >> s2;

    UartConfig cfg(b1, p1, s1);
    cfg.update(b2, p2, s2);

    cfg.print();
