insertion overloading in c++

To overload the insertion operator in C++, you can use the following steps:

1. Create a class for which you want to overload the insertion operator.
2. Define the insertion operator function as a friend function of the class to allow it to access the private members of the class.
3. Inside the insertion operator function, use the ostream parameter to output the data members of the class object.
4. Return the ostream object to allow chaining of insertion operators.

These steps will allow you to overload the insertion operator in C++ and customize the way objects of your class are displayed when using the insertion operator (<<).
