#include<stdio.h>

     );char *gets(char *s



     reads a line from stdin into the buffer pointed to by s
until either a terminating newline or which it replaces with
a null byte ('\0').  No check for buffer overrun is
performed (see BUGS below).

returns s on success, and NULL on error or when end of file
occurs while no characters have been read.  However, given
the lack of buffer overrun checking, there can be no
guarantees that the function will even return.

C89, C99, POSIX.1‐2001.

     LSB deprecates POSIX.1‐2008 marks obsolescent.  ISO C11
removes the specification of from the C language, and since
version 2.16, glibc header files don’t expose the function
declaration if the _ISOC11_SOURCE feature test macro is
defined.

Never use Because it is impossible to tell without knowing
the data in advance how many characters will read, and
because will continue to store characters past the end of
the buffer, it is extremely dangerous to use.  It has been
used to break computer security.  Use instead.
