Example of Function OverridingBelow is a simple example illustrating how overriding works#include <iostream> using namespace std; // Base class class Shape { public: // Virtual method to be overridden virtual void draw() const { cout << "Drawing a shape" << endl; } }; // Derived class...
Functions with incorrect names:For example, if the virtual function in the base class is namedprint(), but we accidentally name the overriding function in the derived class aspint(). Functions with different return types:If the virtual function is, say, ofvoidtype but the function in the der...
The following example shows how function overriding is done in C++, which is an objectoriented programming language −Open Compiler #include <iostream> using namespace std; class A { public: void display() { cout<<"Base class"; } }; class B:public A { public: void display() { cout<...
Note:In C++, many standard library functions are overloaded. For example, thesqrt()function can takedouble,float,int,etc. as parameters. This is possible because thesqrt()function is overloaded in C++. Also Read:

The function definition can be located at the beginning of the program or within a class or structure (we will discuss this in more detail in a later section). The example below showcases the implementation of an inline function in C++. Code Example: #include<iostream> using namespace std;...
You can pass array as an argument to a function just like you pass variables as arguments. In order to pass array to the function you just need to mention the array name during function call like this: function_name(array_name); Example: Passing arrays t
Overloading, overriding, and hidingAny two function declarations of the same name in the same scope can refer to the same function, or to two discrete overloaded functions. If the argument lists of the declarations contain arguments of equivalent types (as described in the previous section), ...
getAnOverridingFunction Gets a directly overriding function. getClassBodyDeclarationEntry Gets the declaration entry for this member function that is within the class body. getEffectiveNumberOfParameters Gets the number of parameters of this function, including any implicit this parameter. getTypeOfThis ...
JavaScript also allows overriding built-in functions in the same way. When we change the code block of a function with the same name as that of a predefined function, it overrides the default function and changes its code to the new one. We will use the Date() function and override it....
