struct className{ virtual return_type fun_name()=0;} We cannot create an object. We can still create a constructor for the abstract class. To call the constructor, we use constructor chaining. The basic purpose of using abstract classes is to maintain a uniform interface inside all derived ...
Variables declared inside the body are called local variables or locals. They go out of scope when the function exits; therefore, a function should never return a reference to a local! C++ MyClass&boom(inti,std::strings){intvalue {i}; MyClass mc; mc.Initialize(i,s);returnmc; } ...
