Just today, I used templates to implement a Finite State Machine to lex some input. … Generally speaking, templates make the most sense when implementing generic algorithms. If you're not implementing a generic algorithm, they don't make that much sense. …

It's called a smart pointer. Specifically, the unique version is in the next Standard as a unique_ptr, and the reference-counted version is in Boost, TR1 and C++11 as shared_ptr. As for it's uses wit …

They are the same thing. The Standardese is "function template" and "class template", however many people (including myself) tend to refer to them as "template function" and "template class", for the …

Quite simply, C++ has a hell of a lot more historical baggage than D. It would be much easier to implement an awful lot of things if it wasn't for the fact that C++ has massive amounts of historical c …

More relevantly, there are simply new techniques and new language features- especially rvalue references, and compiler optimizations are much stronger than they used to be with features like cross-TU …

I learned that virtual member function which justifys the OO Where on earth did you hear that? The crucial tenets of object orientation is encapsulation and abstraction. virtual functions are ju …

This means that any case which needs/benefits from value typing gains big benefits from templates. … Con: Templates are a bitch to compile and use, and they can be fiddly porting between compilers Con: Templates cannot be loaded at run-time (obviously), so they have limits in expressing dynamic data structures …
