I know it's because string lenght too small, but I can't find where lower string is, any suggestion? Please.

There is no problem with this, Y_lees has commented that this warning is when we are trying to store a longer chain to the declared for use with sscanf.

Yes I know but I don't like that when it shows so I wanna make it bigger but cannot found where string is.
