+(DEPRECATED)
+Never use this function.
+BUGS
+       Never  use  gets().   Because  it is impossible to tell without knowing the data in advance how many characters gets() will read, and because gets() 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 fgets() instead.
+       For more information, see CWE-242 (aka "Use of Inherently Dangerous Function") at http://cwe.mitre.org/data/definitions/242.html
