Wilky,
Borland C (and C++) compiler is almost twenty years old, and is DOS only (almost). It is also well behind the current C/C++ standards, and you will need either DOS or 32-bit Windows to use it.
Borland CBuilder (its Windows sibling) is still developed and mainained by Embarcaderro, but it is out of reach for ordinary folks, and probably not the stuff you need.
If this is what your instructor has requested - change your class.
