SOLUTION Solutions to Chapter 13 | C++ CareerCup com pg 76 Let us explain through an example In C++, when you have a class with an overloaded method, and you then extend and override that method, you must override all of the overloaded methods For example: 1 class FirstClass { 2 public: 3 virtual void MethodA (int); 4 virtual void MethodA (int, int); 5 }; 6 void FirstClass::MethodA (int i) { 7 std::cout
Solutions to Chapter 13 | C++ 13 7 Why does a destructor in base class need to be declared virtual? SOLUTION Calling a method with an object pointer always invokes: » the most derived class function, if a method is virtual 2 2 1 Cracking the Coding Interview | Knowledge Based pg 76 » the function implementation corresponding to the object pointer type (used to call the method), if a method is non-virtual A virtual destructor works in the same way A destructor gets called when an object goes out of scope or when we call delete on an object pointer When any derived class object goes out of scope, the destructor of that derived class gets called first It then calls its parent class destructor so memory allocated to the object is properly released But, if we call delete on a base pointer which points to a derived class object, the base class destructor gets called first (for non-virtual function) For example: 1 class Base { 2 public: 3 Base() { cout
