推荐答案
完全取决于所使用的程序。
当然，您可以用眼睛看代码来检查它...... * gg *
that solely depends on the programme used.
of course, you could just look at the code with your eyes to check for it ... *gg*
错误的答案我不期待这个来自网站
bad answer I am not expecting this from the site
所以......我的答案很糟糕，因为你什么都没给我弄明白这个问题？
显然你不尊重有人自愿做这种工作的努力。
so ... my answer is bad because you give me nothing at all to figure out the problem?
obviously you do not honour the effort someone takes voluntarily doing that kind of work.
