That's a pretty simple one. There's no definition of the _Clrscr function anywhere in the translation unit. Visual Studio doesn't come packaged with any form of clrscr as a "standard" library, so you need to consider the following:

  1. Did you declare it somewhere but not define it?
  2. Are you using a third party library that declares it but not link with that library?
  3. Was the code written for a different compiler in a non-standard manner?
