Answer 2

If cout can be copied, then there is duplicate buffers and many stream copied. Not good for performance

Answer 4

No you cannot copy any object defined in the istream or ostream because only one instance of them must have in your program

and in their class, you will see that the copy constructor has been deleted if you look at the cpp source code

Answer 5

No, you cannot create a copy of the cout object. The cout object is an instance of the std::ostream class, which is part of the C++ Standard Library. Stream objects like cout are designed to manage output streams and are not meant to be copied or assigned. This is because they manage resources such as buffers and file descriptors, which can lead to complex issues if duplicated. https://www.my-labcorp.com

I thought to have copy of cout in << operator overloading
