    • ( 6 ) what is the difference bertween overloaded functions and overridden functions?

    • 1) Overloading is a dynamic or run-time binding and Overriding is static or compile-time binding
    • 2) Redefining a function in a friend class is called function overriding while Redefining a function in a derived class is called an overloaded function
    • 3) Overloading is a static or compile -time binding and Overriding is dynamic or run-time binding
    • 4) Redefining a functon in a friend class is called function overloading while redefining a function in a derived class is called as overridden function
