Solution
We can make a class abstract in C++ by making at least one member function as pure virtual function. A pure virtual function is declared by setting it equal to 0 in the class declaration. This means that the function has no body in the base class and must be overridden in any derived class. If a class contains at least one pure virtual function, it becomes an abstract class, which means it cannot be instantiated on its own.
