we learn c++ in school and data structure and a little about oop.
where should i begin .
i already know some about c#,vb

I'd begin by buying Beginning C++ by Ivor Horton (by Wrox.../Wiley) or Sams Teach Yourself C++ in 21 days, both Ivor and Jesse Liberty are good authors, you can't go wrong, although Ivor's books are more comprehensive. And knowing VB won't help :P, just hurt you, but I guess C# won't hurt...
