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