如果无法打开文件,我在C++ void函数中使用exit.这样做是好的做法吗？

 void ReadData()
 {
      ofstream myfile ("example.txt");
      if (! myfile.is_open())
      {
            cout << "Unable to open file";
            exit(0);
      }
      else {
            myfile << "This is a line.\n";
            myfile << "This is another line.\n";
            myfile.close();
      }
 }
