what is the overflow tool in C language?

During a interview, I was asked what kind of overflow tool in C language you used? I do not know any tool like that.

And in C++, what kind of tool used to track the versions of c++ files?

D开发者_运维百科o anyone know about that?

I assume that "overflow" in this context is referring to "buffer overflow". There are a range of memory debuggers available, that can detect this kind of error. One popular example is Valgrind.

Tracking file versions is generally done with a revision control system (RCS), but this isn't specific to C++. There are zillions of RCSs available, such as Sourcesafe, Perforce, ClearCase, CVS, SVN, Git, Mercurial.

The term is non-specific. A buffer overflow tool? A value overflow tool? What? Either your interviewer was off track, or perhaps you don't recall the exact term he used.

I even tried Googling the term and it's clearly not a generally accepted one.
