UART Config Class

#include <iostream>
using namespace std;

// Define UartConfig class here
// <write your code>
class UartConfig{
    private: 
        int baudrate; 
        int parity; 
        int stopBit; 
    public: 
        UartConfig(int b, int p, int s): baudrate(b), parity(p), stopBit(s){}
        void update(int b, int p, int s) {
            baudrate = b; 
            parity = p; 
            stopBit = s; 
        }
        void print() {
            cout << "baud=" << baudrate
             << " parity=" << parity
             << " stop=" << stopBit;
        }
};

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();
