First, gets() is the antichrist. If you want to write decent programs, use
fgets() which allows you to specify a maximum length, thus ensuring your
buffer is not overrun. This is discussed in the comp.lang.c FAQ.

IIRC, scanf() leaves the trailing newline in the input stream. The next time
gets() is called, it will read in this newline and instantly return. The
solution is to not intersparse different types of input functions. scanf() and
gets() do not get along. IMHO, the best solution is to read in an entire line
of text with fgets() and parse it with sscanf(). This is also discussed in
the comp.lang.c FAQ.
