UART Config Class

#include <iostream>
using namespace std;

// Define UartConfig class here
// <write your code>
class UartConfig{
    private:
        int baudrate;
        int parity;
        int stopBits;
    
    public:
        UartConfig(int b, int p, int s):baudrate(b), parity(p),stopBits(s){}

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

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

        } 

};

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();
