gets command in c

hello, i want to ask about the "gets" command (which has the same function as scanf). i use the ubuntu 11.10 and has no problem in the program with the "gets"...

but, when i try it in another pc with ubuntu 10.10 (if i'm not wrong, it has a different environment with ubuntu 11.10).
my question is: is that true? i mean, is that true that the gets command doesn't work in ubuntu 10.10? and is there any subtitution? and is there any advice?

thanks in advance \/
