Strictly speaking neither of these programs is ok. In the first one
you have allocated how many bytes for ``line''? (In is supposed
to be an array). In the second, which uses a char * instead of
an array, how many bytes have you allocated to store them?

None.

If you try:
		char line[5];

things will look a bit better -- remember to allocate 1 extra
byte to store that pesky null at the end of every (normal) C
string. Alternatively,
		char *line;
		line = malloc(5);
should also work.
