WebIntroduction. Upcasting and downcasting are an important part of C++. Upcasting and downcasting give a possibility to build complicated programs with a simple syntax. It can be achieved by using Polymorphism. C++ allows that a derived class pointer (or reference) to be treated as a base class pointer. This is upcasting. WebThese limitations are imposed by the very nature of dynamic polymorphism: as the exact types of the elements accessed through base 's interface are not known, an indirection through base * (a particular form of type erasure) is required.There is however a critical observation: even though derived types are not known when traversing a std:: vector < …
