If you write void *p; p doesn’t point to a void! In C and C++, any time you need a void pointer, you can use another pointer type.

Overloading simply involves having a method with the same name within the class.

Example for Over loading

The Answer is 2. printf function returns the number of characters printed, so it returns 3 and "tim" is already printed due to the call to printf("tim"). So the output is tim 3.
