运行下面的代码，屏幕上将输出（    ）。

      }

      return a / b;

}

int main() {

      int x = 10;

      int y = 0; // 设为 0 会导致除零错误

      try {

            int result = divide(x, y);

            cout << "result: " << result << endl;

} catch (const runtime_error& e) {

            cout << "caught an exception: " << e.what() << endl;
