We have already known operator means it will be performed some kind of operations between two are more operands. likewise here ,,"cout " perform an input operation by using the symbol ">>" but the same time it is an object.
How it is possible?
Because cout is a object for (derived class or sub class) ostream .and it's main class is "iostream.h" so the answer is (c) OBJECT.

<< is an operator which can print data on a console.
"<<" is an operator that can be overloaded in such a way that can print data on console in ostream class.
cout is an object, when ever cout << "Raja sekhar"; executes.
Compiler class as cout.operator<< (.).

Std::cout and std::cin are global objects of classes std::ostream and std::istream, which they've overloaded operator << and >>. You should read about operator overloading. The Cout is the object of type ostream. Cin is the object of type istream.

In C programming language, We consider printf and scanf to be functions. when it comes to cout and cin, in C++ what are they?
I mean they cant be functions as they are not followed by parenthesis, so they are not functions .cout is an object of the class.

Object is the simple variable of a class. So if we will open <iostream> header then we can found the statement.
Extern ostream cout; means cout is the variable of ostream class so. For this reason it is an object.
Extern ostream cout; means cout is the variable of ostream class so. For this reason it is an object.

cout is a object and not a function. cout is an output stream object that refers to the monitor whereas cin refers to the keyboard.Both are defined in the header file <iostream.h>

The cout is an object of class ostream that represents the standard output stream oriented to narrow characters (of type char). It corresponds to the C stream stdout.

In c++, iostream is the header file, which contains i stream and o stream, jectathis two are objects, so cin is istream object and cout is ostream object.

cout is an object because it is an object of ostream and we use the header file <iostream> here. It allows both input and output operations.
