is polymorphism possible in c

Polymorphism is a feature of OOPs that allows the object to behave differently in different conditions. This does not mean, however, that it is impossible to model the corresponding behavior with the regular features of C: it is possible to build a library that lets you produce behavior that looks like polymorphism, for example, by using arrays of function pointers. Yes. In overloading, the method / function has a same name but different signatures. Polymorphism is about selecting different actions for different cases. In the preceding program we declare the Virtual method that returns 10 and the same method we are using in the class Amount using the override keyword that at runtime returns 500 without changing the values of the method, even the names are the same so the example above shows runtime polymorphism.
