（1） freopen("filepath", "w", stdout );
warning C4996: 'freopen': This function or variable may be unsafe. Consider using freopen_s instead. To disable deprecation, use _CRT_SECURE_NO_WARNINGS. See online help for details.
然而怎么改成freopen_s 呢？！！sorry，我不知道，望知之者相告！！
(2) 我只能这样处理了。。。。#pragma warning(disable:4996)
