yeah.... in call by reference, the real object is passed and whatever are the changes done to that object, they are reflected even on returning back from the function.
so actual values are passed rather than the copy of them as in case of call by value.

Explain the passing parameters as function in Call by Value and Call by Reference and then distinguish between them?
Call by value essentially passes a copy of an object's value whereas call by reference essentially passes the object itself. Pass by reference is the preferred method whenever possible as call by value will automatically invoke the object's copy constructor, which is often unnecessary, especially if the object is not affected by the function call (pass by constant reference).
How do you if an object is receiving more heat then it is passing on receiving less heat than it is passing on or receiving and passing on the same amount?
You can determine if an object is receiving more heat than it is passing on by monitoring its temperature increase. If the object's temperature is rising, it is receiving more heat than it is passing on. If the object's temperature is dropping, it is passing on more heat than it is receiving. If the object's temperature remains constant, it is receiving and passing on heat at the same rate.

What happens in volleyball when a foul is committed but play continues?
you play the whistle; the ref has the last word. You can ask for a time out, and then talk to your ref, but if it's a good ref and they don't call it then it usually doesn't count.
Why you pass something by reference and then make it const while call by reference mean you want to change it?
Call by reference does not necessarily mean you want to change something. It simply means that you are passing a pointer to the object rather than the object itself. This can be cost effective if the object is large, in comparison to a pointer. Making the call by reference const is an effective tool for doing this when you do not intend to modify the object, and you want to make sure you don't accidentally do so.

What colour is refracted most when passing triangular prism?
violet is most refracted when passing through a triangular prism because refractive index of violet is more and dispersion is directly proportional to ref index
