向txt文件中寫數據（每行三個數據）

try
{
CFile file(_T("E:\\1_3D.txt"), CFile::modeCreate | CFile::modeWrite);
char buf[128] = { 0 };
int j;
for (int i = 0; i<vect3DAlignFace.size(); i++)
{
//j = i;
sprintf(buf, "%.3f %.3f %.3f\r\n", vect3DAlignFace[i].x, vect3DAlignFace[i].y, vect3DAlignFace[i].z);
file.Write(buf, strlen(buf) * sizeof(char));
}
file.Close();
}
catch (CFileException* e)
{
e->ReportError();
e->Delete();
}
