A friend of mine is a deep-level PERL programmer; I believe he’s done some work on the interpreter core itself.
His employer wants him to learn C++. So he’s asking for tips on learning this language; he already has a decent knowledge of C, so he’s not starting entirely from scratch.
I recommended that he read the perltrap page, find the section on C++, and read it in reverse. Any other ideas?
C++ is closer to C than to Perl, I would say. But I wouldn’t say that either language is a great leap-off point for learning C++.
But essentially what he needs to learn is (in no particular order):
Object Oriented code*
Templates
Try/Catch statements
Overloaded Operators
Other than that, his knowledge of C should be fine enough. But he might do some good to look up the above items just to get a first overview before jumping into a C++ book.
But my biggest warning is that you do not want to try learning C++ from Stroustrup (the language creator)'s book. It sucks lonk as far as presenting topics in logical order, or in English for humans.
