Example for polymorphism in c++
WebAn abstract class in C++ has at least one pure virtual function by definition. In other words, a function that has no definition and these classes cannot be instantiated. The abstract class’s child classes must provide body to the pure virtual function; otherwise, the child class would become an abstract class in its own right. WebMar 3, 2016 · Parametric polymorphism means that a function's type is parameterized by another type and thus the function will work for all potentially provided types. For this to work, the function can assume nothing about the type except what is true for all types. The simplest example is the type of the identity function: template T identity ...
