43. Using Namespace Directive

#include <iostream>
using namespace std;

namespace Config {
    int baudRate = 9600;
    int threshold = 50;
}

int main() {
    // your code here: add using namespace statement
    int bd = Config::baudRate;
    int th = Config::threshold;
    // your code here: print baudRate and threshold
    printf("Baud: %d, Threshold: %d\n", bd, th);
    return 0;
}
