Which operator is overloaded for cout operation?
To get cout to accept a Date object after the insertion operator, overload the insertion operator to recognize an ostream object on the left and a Date on the right. The overloaded << operator function must then be declared as a friend of class Date so it can access the private data within a Date object.

Can we overload << operator in C++?

Answer. The “c” in cout refers to “character” and ‘out’ means “output”, hence cout means “character output”. The cout object is used along with the insertion operator << in order to display a stream of characters. The general syntax is: cout << varName; Or.
