Introduction
Operator overloading is a powerful feature of C++ that allows you to redefine the behavior of operators for user-defined types. However, when using operator overloading, you may encounter errors such as “no match for ‘operator>>'”. This error occurs when the compiler cannot find a suitable definition for the overloaded operator. In this article, we will discuss the causes of this error and how to solve it.
Solution
The error “no match for ‘operator>>'” occurs when the compiler cannot find a suitable definition for the operator>> function. This usually happens when the user has not defined the operator>> function for a particular type of object. To solve this error, the user must define the operator>> function for the object type in question.
You have to change the get_name() to return a non-const reference, like string& get_name(); to get it working/compile. But will look strange.
What you can do instead is pass the member name directly
iss >> employee.name;
that’s what friends do.
And don’t forget to return the stream is.

Solving Operator Overloading Error: No Match for ‘operator>>’
Operator overloading is a powerful feature of C++ that allows you to define how operators work with your own classes. However, it can be tricky to get right, and one common error is the “no match for ‘operator>>'” error. This error occurs when you try to use the >> operator with a class that doesn’t have an overloaded version of the operator.
The solution to this error is to define an overloaded version of the >> operator for your class. This is done by creating a function with the following signature:
std::istream& operator>>(std::istream& is, MyClass& obj);
Where MyClass is the name of your class. This function should read the data from the std::istream and store it in the object of type MyClass. Once you have defined this function, the compiler will be able to find a match for the >> operator and the error should go away.
It’s important to note that the >> operator is only used for input. If you want to use the << operator for output, you will need to define an overloaded version of that operator as well.
Operator overloading can be a tricky concept to understand, but with a bit of practice it can be a powerful tool for creating expressive and readable code. Hopefully this article has helped you understand how to solve the “no match for ‘operator>>'” error.
