- Ans.
References in C++ allow a variable to refer to another variable's memory address.
References are declared using the '&' symbol.
They are often used as function parameters to avoid copying large objects.
References cannot be null and cannot be reassigned to refer to a different object.
They are commonly used in operator overloading to modify the original object.
Example: int x = 5; int& y = x; y++; // x is now 6.
Example: voi...
Answered by AIAdd your answer- Q27. What is a static function in a C++ class? Why is it used? How to call a static function of class from any part of the code
- Ans.
Static function in C++ class is used to access class-level data without creating an object.
Static functions can be called using the class name and scope resolution operator (::)
They cannot access non-static data members of the class
They can be used to implement utility functions that do not require access to object-specific data
Static functions are shared among all objects of the class
