'this'pointer can be used to return the reference of current/calling object, here is an example where an object is being initialized with another object using parameterized constructor. #include <iostream>using
C program not linking to CRT calls memset() for unknown reasons C/C++ : converting std::string to const char* I get the error : left of '.c_str' must have class/struct/union type is 'char *' C# to C++ dll - how to pass strings as In/Out parameters to unmanaged functions that ...
cython is generating C code that produces an "incompatible-pointer-types" when compiled with gcc. The problem appears in inlined methods of a derived class. In the folloing code, the methodDerived.fun1receives aBase*where the method expects aDerived* Code to reproduce the behaviour: #example ...
I noticed a small glitch in the code you sent - "subroutine ... end function". This suggests to me that you did not actually build the program. For us to help out, it would be very convenient to have something that builds without editing, and that is ...
However, the passed argument must be of type BC whereas I would like to override AF with an implementation within the DC, having the same name, that would be passed a derived-class argument. However, this results in an error.4. It seems that the only way around this situation is to ...

The weak lgc-transitions are derived from the strong transitions in the standard way, and induce notions of weak lgc-equivalence, weak lc-equivalence, and weak gc-equivalence, denoted respectively ≈lgc,≈lc and ≈gc. We recall from [100] the main results concerning these equivalences. The fir...
BaseClass { public: Derived(); // Derived class constructor. void Func2(); }; // Declare a pointer to member function Func2. void (Derived::*pmfnFunc2)() = &Derived::Func2; int main() { BaseClass ABase; Derived ADerived; (ABase.*pmfnFunc1)(); // OK: defined for BaseClass....
If the original pointer is pointing to a base class subobject within an object of some polymorphic type, dynamic_cast may be used to obtain a void* that is pointing at the complete object of the most derived type. Pointers to void have the same size, representation and alignment as ...
