const vs constexpr on variables
...mple a g++ extension for that), but that does not mean it's strictly legal C++ (though some more recent C or C++ standard made it legal, I forgot which one). As for differences in compiletime constants, template parameters and use as enum initializer are the only two notable differences between cons...

C++ where to initialize static const
...eturn 42; } class foo { static const int i = f(); /* Error! */ } Note that C++11 allows calling 'constexpr' functions: constexpr int f() { return 42; } class foo { static const int i = f(); /* Ok */ }

Where is shared_ptr?
...
There are at least three places where you may find shared_ptr:
If your C++ implementation supports C++11 (or at least the C++11 shared_ptr), then std::shared_ptr will be defined in <memory>.
If your C++ implementation supports the C++ TR1 library extensions, then std::tr1::shared_ptr will ...
push_back vs emplace_back
...it is strictly equivalent to push_back(Type&& _Val).
But the real C++0x form of emplace_back is really useful: void emplace_back(Args&&...);
Instead of taking a value_type it takes a variadic list of arguments, so that means that you can now perfectly forward the arguments and cons...
Why does C++ not allow inherited friendship?
Why is friendship not at least optionally inheritable in C++? I understand transitivity and reflexivity being forbidden for obvious reasons (I say this only to head off simple FAQ quote answers), but the lack of something along the lines of virtual friend class Foo; puzzles me. Does anyone know ...
What is the difference between exit and return? [duplicate]
...es the process immediately.
Now there are also issues that are specific to C++.
C++ performs much more work than C when it is exiting from functions (return-ing). Specifically it calls destructors of local objects going out of scope. In most cases programmers won't care much of the state of a progra...
What's the result of += in C and C++?
...
Semantics of the compound assignment operators is different in C and C++:
C99 standard, 6.5.16, part 3:
An assignment operator stores a value in the object designated by the left operand. An
assignment expression has the value of the left operand after the assignment, but is not an
