Overloading: providing multiple behaviour to same object with respect to attributes of object.see in programming, every thing is object. u r program also an object, function is also an using function overloading, we can  call specific behaviour of that according to what attributes we set at  compiled time.mean we don't need to write different function name for different action.

Function overloading exhibits the behavior of polymorphism which helps to get different behaviour, although there will be some link using same name of function. Another powerful use is constructor overloading , which helps to create objects differently and it also helps a lot in inheritance.

For eg: Say a method called addUs(a,b) adds a and b.So the definition will be int addUs(int a, int b){ return a+b;}But now if you want your arguments to be Objects of a class sayclass Demo{int height;int width;}You want the same function addUs() to return a new object which would have attributes height and width having values as sum of the height & width of the 2 arguments passed.So now the definition would be:Demo addUs(Demo a, Demo b){ this.height = a.height + b.height; this.widht = a.widht + b.width; return this;}

Using the concept of function overloading; we can design a family of functions with one function name but with different argument lists. the function would perform different operations depending on the argument list in the function call.
