    Re: C++: can i create Polymorphism without 'virtual'?

    When using polymorphism, the type of the pointer used should be a pointer to the base class. So

    Test(ClassDerived *clsPointer) {

    Test(ClassDerivedNull *clsPointer) {
    So that
    int main() {
    	ClassDerivedNull n;
    	Test t2(&n);
    	ClassDerived d;
    	Test t1(&d);

    Move NULL implementation
    MouseClick REAL implementation
    Move NULL implementation

    All advice is offered in good faith only. All my code is tested (unless stated explicitly otherwise) with the latest version of Microsoft Visual Studio (using the supported features of the latest standard) and is offered as examples only - not as production quality. I cannot offer advice regarding any other c/c++ compiler/IDE or incompatibilities with VS.
