sscanf() reads the input from a memory region and thus you already know the
maximum amount of memory that will be needed. This is only neccessary for
strings, though, because scanf() reads up to the next whitespace or CR. This
means you provide i.e. 30 characters for a string and the user types in 40 and
BINGO! your program crashes.
