I am facing a problem that I cannot see how it is solvable without #defines or incurring a performance impact although I am sure that someone can point me to a solution.
Short Description: I am iterating over a vector calling a virtual function on every object in the vector in order to execute a sequence of actions.The vector is of the base class as is the iterator.Al
This is not a question about how they work and declared, this I think is pretty much clear to me. The question is about why to implement this?
I\'m having a bit of trouble using virtual functions in C++, and I might be misusing them in a constructor. The problem is that when linking a component lib (written by me) into my final executable, a
I noticed that If I run strings on my program which was compiled by g++ the output contains the names of various classes that it uses.
With the struct definition given below... struct A { virtual void hello() = 0; }; Approach #1: struct B : public A {
I have two classes: class x { public: virtual void hello() { std::cout << \"x\" << std::endl;
In brief: From a C++ base-class pointer which points to an instance of a derived class, how can one determine at run-time whether a non-pure virtual function (with an implementation in the base class)
Is开发者_开发百科 it possible for an inherited class to implement a virtual function with a different return type (not using a template as return)?In some cases, yes, it is legal for a derived class t
