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
    using namespace Config;

    // your code here: print baudRate and threshold
    cout<<"Baud: "<< baudRate<< ", Threshold: "<< threshold;
    return 0;
}
