Consider the following code: struct Base {}; struct Derived : public virtual Base {}; void f() { Base* b = new Derived;
I\'m working on an embedded platform (ARM) and have to be careful when dealing with bit patterns. Let\'s pretend this line is beyond my influence:
I\'m trying to convert a bit of VC 6.0 C++ code to C#. Specifically, I\'m parsing through a binary dat file and I\'ve run into a problem converting this bit of code:
First of all, this is not a duplicate of Why do we have reinterpret_cast in C++ when two chained static_cast can do it\'s job?.
There\'s a set of questions regarding c开发者_StackOverflow中文版ross-casts (cast from T1* to unrelated T2*), for example this and this. The answer usually goes like this: reinterpret_cast is implemen
See the code below. a) Does, in this case (simple inheritance, no virtual members), the static cast in B::df() have any overhead (whatsoever)? I found some conflicting answers to similar questions, t
Why static_cast cannot downcast from a virtual base ? struct A {}; struct B : public virtual A {}; struct C : public virtual A {};
Ran across this in code I\'m working 开发者_StackOverflow社区through: double part2 = static_cast<double>(2) * somthing1
I want to make sure that *this != &rhs in the assignment operator. But it won\'t compile. Any suggestions?
I am trying to learn about static_cast and reinterpret_cast. If I am correct the standard (9.2.18) says that reinterpret_cast for pod data is safe:
