Which statement is true about function overriding in C++?a)Overriding ...
Function overriding in C
Function overriding is a feature in object-oriented programming that allows a derived class to provide a different implementation of a method that is already defined in its base class. When a derived class overrides a function, it provides its own implementation of the function, which is used instead of the base class implementation when the function is called on an object of the derived class.
Understanding the given options:
a) Overriding can only be done in derived classes: This statement is incorrect. Overriding can be done in both derived classes and the base class.
b) Overriding can only be done for private member functions: This statement is incorrect. Overriding can be done for both private and public member functions.
c) Overriding changes the return type of the base class function: This statement is incorrect. Overriding does not allow changing the return type of the base class function. The return type of the overridden function in the derived class must be the same as or covariant with the return type of the base class function.
d) Overriding allows a derived class to provide a different implementation of a base class function: This statement is correct. Overriding allows a derived class to provide its own implementation of a method that is already defined in the base class. When the function is called on an object of the derived class, the overridden implementation is executed instead of the base class implementation.
Conclusion:
The correct statement about function overriding in C is that overriding allows a derived class to provide a different implementation of a base class function. This feature enables polymorphism and allows objects of different classes to be treated interchangeably based on their common base class type. Overriding is a powerful mechanism in object-oriented programming that promotes code reuse and flexibility.

Which statement is true about function overriding in C++?a)Overriding ...
Function overriding allows a derived class to provide a different implementation of a base class function. It is achieved by declaring a function with the same name and signature in the derived class.
