Question 12.18

I'm reading a number with scanf %d and then a string with gets(), but the compiler seems to be skipping the call to gets()!

scanf %d won't consume a trailing newline. If the input number is immediately followed by a newline, that newline will immediately satisfy the gets().

As a general rule, you shouldn't try to interlace calls to scanf with calls to gets() (or any other input routines); scanf's peculiar treatment of newlines almost always leads to trouble. Either use scanf to read everything or nothing.
