Differentiate between function overloading and function overriding

Question

Differentiate between function overloading and function overriding in C

User · Answer

in overloading function with same name having different parameters whereas in overridding function having same name as well as same parameters replace the base class to the derived class  inherited class

User · Answer

1 Function Overloading is when multiple function with same name exist in a class  Function Overriding is when function have same prototype in base class as well as derived class   2 Function Overloading can occur without inheritance  Function Overriding occurs when one class is inherited from another class   3 Overloaded functions must differ in either number of parameters or type of parameters should be different  In Overridden function parameters must be same   For more detail you can visit below link where you get more information about function overloading and overriding in c   https   googleweblight com i u https   www geeksforgeeks org function-overloading-vs-function-overriding-in-cpp  amp hl en-IN

Function overloading is done when you want to have the same function with different parameters  void Print string s    Print string void Print int i    Print integer   Function overriding is done to give a different meaning to the function in the base class  class Stream  A stream of bytes   public virtual void Read     read bytes    class FileStream Stream  derived class   public override void Read     read bytes from a file   class NetworkStream Stream  derived class   public override void Read     read bytes from a network

Overloading a method  or function  in C   is the ability for functions of the same name to be defined as long as these methods have different signatures  different set of parameters   Method overriding is the ability of the inherited class rewriting the virtual method of the base class   a  In overloading  there is a relationship between methods available in the same class whereas in overriding  there a is relationship between a superclass method and subclass method    b  Overloading does not block inheritance from the superclass whereas overriding blocks inheritance from the superclass    c  In overloading  separate methods share the same name whereas in overriding  subclass method replaces the superclass    d  Overloading must have different method signatures whereas overriding must have same signature

Function overloading is same name function but different arguments                                         Function over riding means same name function and same as arguments

User · Answer

In addition to the existing answers  Overridden functions are in different scopes  whereas overloaded functions are in same scope

User · Answer

You are putting in place an overloading when you change the original types for the arguments in the signature of a method   You are putting in place an overriding when you change the original Implementation of a method in a derived class

User · Answer

Overloading means having methods with same name but different signature Overriding means rewriting the virtual method of the base class

User · Answer

Function overloading may have different return types whereas function overriding must have same or matching return types

User · Answer

Overriding means  giving a different definition of an existing function with same parameters   and overloading means adding a different definition of an existing function with different parameters   Example    include  lt iostream gt   class base      public        this needs to be virtual to be overridden in derived class     virtual void show   std  cout lt  lt  I am base          this is overloaded function of the previous one     void show int x  std  cout lt  lt   nI am overloaded         class derived public base      public        the base version of this function is being overridden     void show   std  cout lt  lt  I am derived  overridden          int main        base  b      derived d      b  amp d      b- gt show       this will call the derived overriden version     b- gt show 6      this will call the base overloaded function     Output   I am derived  overridden  I am overloaded

User · Answer

Function overloading - functions with same name  but different number of arguments  Function overriding - concept of inheritance  Functions with same name and same number of arguments  Here the second function is said to have overridden the first
