VS中MFC读取txt数据

        CFileDialog open_dlg(true,NULL , NULL , OFN_FILEMUSTEXIST | OFN_READONLY | OFN_PATHMUSTEXIST , TEXT("文本文件(*.txt)|*.txt|所有文件(*.*)|*.*|") , NULL);

error.GetErrorMessage(szError, 1024);
CString strErr;
strErr.Format(_T("创建匹配列表文件 match_list.txt 失败！"));
AfxMessageBox(strErr);
return;

}

        double **s;

s=(double **)malloc(100*sizeof(double *));    //s为存放txt文件数据数组
for(int i=0;i<15;i++)
