we can develop more than one function with the same name

function overloading is essential to allow the function name (for example the constructor) to be used with different argument types.

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 object.

by 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 say
class 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;
}

Function overloading is one or more funcation has different number of argument or diffrent type of argument but all have same return type otherwise it create ambitious to knowing which function u may want to call. It is also save the memory space and provide compile time polymorphysm.

In function overloading memory is saved, but its time consuming & then we use inline function

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.

We can Define Multiple Function with same name to perform same task. Compiler can not compile a function separately

Saves on memory exhibits code reusability as same function can be reused but with different parameters each time.

With the help of function loading we can use multiple function without declare again and again as per our requirement we can use our parameters in same function and call them from our subclasses.
