Difference between overloading and overriding in C++ ?

Question

Please explain with basic example.Am new to programming

Answer 1

Few points should help you:

• Overloading is when multiple function with same name exist in a class. Overriding is when function have same prototype in base class as well as derived class.
• Overriding occurs when one class is inherited from another class whereas overloading can occur without inheritance.
• Overloaded functions must differ in either number of parameters or type whereas in Overridden function parameters must be same.

Answer 2

1.In overloading,there is a relation ship between methods available in the same class where as in overridding,there is relationship between a super class method and subclass method.
2.Overloading doesn't block inheritence from the superclass where as overridding blocks inheritence.
3.In overloading,seperate methods share the same name where as in overridding,subclass methods replaces the superclass.
4.Overloading must have different method signatures where as overriding must have same signature.

Example

Overriding

public class MyBaseClass
{
    public virtual void MyMethod()
    {
        Console.Write("My BaseClass Method");

    }
}
public class MyDerivedClass : MyBaseClass
{
    public override void MyMethod()
    {
        Console.Write("My DerivedClass Method");

    }
}

Overloading

int add(int a, int b)
int add(float a , float b)
