gets, fgets - get a string from a stream
char *fgets(s, n, stream)
Gets reads a string into s from the standard input stream stdin.
The string is terminated by a newline character, which is replaced
in s by a null character. Gets returns its argument.
Fgets reads n-1 characters, or
up through a newline character,
whichever comes first, from the stream into the string s. The last
character read into s is followed by a null character. Fgets
returns its first argument.
