Overriding standard C library functions in C++ program, Overriding is a completely different concept from overloading. You override a virtual member function. No overloading takes place here. What actually happens is you are defining printf with the exact same signature as stdio.h declares. So i...
Otherwise, the program will simply compile but the virtual function will not be overridden.Some of these possible mistakes are:Functions with incorrect names: For example, if the virtual function in the base class is named print(), but we accidentally name the overriding function in the derived...
In inheritance where base class and derived class have same function declaration but different definitionFunctionthen this is known as function overriding.To override a method, make the function open in base class and addprefix override before function definition in derived class....

In this program, we overload theabsolute()function. Based on the type of parameter passed during the function call, the corresponding function is called. Example 2: Overloading Using Different Number of Parameters #include<iostream>usingnamespacestd;// function with 2 parametersvoiddisplay(intvar...

C++ lets you specify more than one function of the same name in the same scope. These functions are calledoverloadedfunctions, oroverloads. Overloaded functions enable you to supply different semantics for a function, depending on the types and number of its arguments. ...
If the base class function isn't declared asvirtual, then the derived class function is said tohideit. Both overriding and hiding are distinct from overloading. Block scope is strictly observed. A function declared in file scope isn't in the same scope as a function declared locally. If ...
