Please give a example of the same.

The right answer here should be (B). As the compiler differentiates the functions with same name based on.

I) No.of arguments.

II) Type of arguments.

The return type is not a taken into account in case of function overloading.

Thus (A) is ruled out.

Its just like function overloading.

Double can take 4 byte, but int can take only 2 byte.

Yes, I agree to what ajith said.

Because function overloading is according to the change in parameter not in return type., here char function() contain same data type so it is not accepted.

In function overloading function names are same for different functions but all these same named function should have different arguments and type of arguments and return type should be same. That's why answer is B.

It uses the concept of function overloading which states that there could be multiple no. of functions with the same name, but the signature list must be different (the no. of and type of parameters).

In function overloading concept the function name is same but the parameters passing through it are different.

I think here is the case of overriding not overloading guys.

Because in overriding type f.name and parameter should be same.
