Ok.

This is not true. This method may be even worse, because changing the platform may cause unexplained waiting and lease congestion, huh, huh.
Because standard carriage returns / line feeds / spaces / tabs are delimiters for scanf, they should be ignored.

But I do n’t know what Microsoft is doing. This is not the case since the DOS era. Instead, it makes scanf read a newline, which makes people lose their temper.

Oh, I was wrong. --b.
Even if it is scanf, you give getchar, sorry.

Er, I haven't considered the situation where the buffer is empty. It seems that there is no better solution than fflush.
