ostream

[jyothi...@gmail.com]

Hi,

I have a question about what is happening in this video at 00:19:02 -

http://www.youtube.com/watch?v=_Mb9NbkNVcA#t=1142s.

do we use ostream always if we want to overload cout? can we use other names too? why it is passing with &? cant we use * instead?.

Thanks!

Yes. Because cout is a function which returns takes parameter and returns ostream class type object reference. As it is returning a reference and taking a reference type object, we need to mention &. Therefore, * will not work as it is used for pointer.
