//////////////////////////////////////////////////////////////////////////////////////////////////////////// Question://     This program will probably crash. Where and why?//// Problem: //     Based on the code: Inheritance & Virtualization Problems.//// Solution://     Common language mistake when defining object inheritance; that is if you forget //     what it's for, and why. ////     By default, Class C inherited Class B for 'private' use.//     This would result as 'inaccessable' and result in a runtime 'crash',//     'compile error' or even both, depending on your compiler. Thus, //     'class C : public A, B' was and needs to be changed to 'class C : public A, public B'.////     Constructors were added for good practice, which should of been done in the first place,//     and virtual destructors were added to ensure proper 'virtual' destruction of the objects.//     Deleting objects without proper virtualization would in short confuse memory deallocation//     when 'delete' is called on the object and crash the program.//    ////////////////////////////////////////////////////////////////////////////////////////////////////////// class A{public:    A() { }    virtual ~A() { }    int x;};class B{public:    B() { }    virtual ~B() { }    int y;};class C : public A, public B{public:    C() { }    virtual ~C() { }    int z;};int main(){       A* a = new C();    delete a;          B* b = new C();    delete b;    return 0;}
