gets()是用来读入一行的，不是读一串字符，你改的是不对的

zz from google: 

The gets function takes one parameter, the string in which to store the data read. It reads characters from standard input up to the next newline character (that is, when the user presses <RETURN>), discards the newline character, and copies the rest into the string passed to it.
