问C++中的CSV文件？

    ofstream Morison_File ("linear_wave_loading.csv");         //Opening file to print info to
    Morison_File << "Time Force(N/m)" << endl;          //Headings for file
    for (t = 0; t <= 20; t++) {
      u = sin(omega * t);
      du = cos(omega * t); 
      F = (0.5 * rho * C_d * D * u * fabs(u)) + rho * Area * C_m * du; 

      cout << "t = " << t << "\t\tF = " << F << endl;
      Morison_File << t;                                 //Printing to file
      Morison_File << F;

    }

     Morison_File.close();
