using namespace std; // optional, could say std::cout and std::endl below instead

const int SUCCESS = 0; // by convention, where non-zero results are error codes

int main (int, char**) { // argc and argv not used, but their types are specified

    cout << "hello, world!" << endl; // procedural: has an effect

    return SUCCESS; // functional: returns a success/failure code
