gets_s() function is not working on my compiler. I am using codeblocks with GCC.
This is the error :
undefined reference to '_imp_gets_s.
Can anyone please tell me how to resolve this error.

`gets_s` it self is an error, use `fgets()`. – Iharob Al Asimi Apr 23 '15 at 10:51

Don't use `gets` use `fgets()` – Gopi Apr 23 '15 at 10:51

But c11 states that gets function no longer used.gets_s is used instead – jashan Apr 23 '15 at 10:52

gets_s() is an extension. Not part of std C, see: http://stackoverflow.com/q/12893774/2235885 – joop Apr 23 '15 at 11:09

2@joop, to be exact, Annex K is an *option*, and this is the problem here, glibc doesn't implement it. – Jens Gustedt Apr 23 '15 at 11:22

You should be using fgets() over gets() or gets_s().
Referrring C11, §K.3.5.4.1, paragraph 6,
The
fgets()function allows properly-written programs to safely process input lines too long to store in the result array. In general this requires that callers offgets()pay attention to the presence or absence of a new-line character in the result array. Consider usingfgets()(along with any needed processing based on new-line characters) instead ofgets_s().
