UART Initialization Defaults

#include <iostream>
using namespace std;
 
// Write your function here
void initUART(int & baud){
    cout << baud << " N" << " " << 1;
}

void initUART(int &baud, char &parity){
    cout << baud << " " << parity << " " << 1;
}

void initUART(int &baud, char &parity, int &stopBits){
    cout << baud << " " << parity << " " << stopBits;
}
 
int main() {
    int baud, mode;
    cin >> baud >> mode;
 
    if (mode == 0) {
        // use all default values
        initUART(baud);
    } else if (mode == 1) {
        char parity;
        cin >> parity;
        initUART(baud, parity);
    } else if (mode == 2) {
        char parity;
        int stopBits;
        cin >> parity >> stopBits;
        initUART(baud, parity, stopBits);
    }
 
    return 0;
}
