Why the GNU compiler gives the warning while using gets() ?

When I use gets() function, the gcc compiler gives the warning - gets function is dangerous and should not be used. What is the problem in using it and how to avoid it ?

gets() will overrun your buffer since it fetches characters until a \n or you run out of file. Not good. You need to use a function that fetches a known numberb of characters so you can control your input.
