How to Overload the (+) Plus Operator in C++? Last Updated : 14 Feb, 2024 Comments Improve Suggest changes Like Article Like Report In C++, operator overloading is a feature of the OOPs concept that allows you to redefine the behavior for different operators when they are used with objects of user-defined classes. The plus operator (+) is a binary operator generally used for addition. In this article, we will learn how to overload the (+) plus operator in C++ for a user-defined class. Overloading the Plus(+) Operator in C++ To overload the plus operator, we have to create an operator+ function inside our class and define its behavior inside this function's body. The following syntax shows how to do it: myClass operator+ (const myClass& obj) const { // new behaviour }C++ Program to Overload the Plus(+) Operator for a Class C++ // C++ program to demonstrate operator overloading of plus // operator #include <iostream> using namespace std; // Class definition class MyClass { private: int value; public: // Constructors MyClass(): value(0){} MyClass(int val): value(val){} // Overloaded operator + MyClass operator+(const MyClass& other) const { MyClass result; result.value = this->value + other.value; return result; } // Getter method int getValue() const { return value; } }; int main() { // Create objects MyClass obj1(5); MyClass obj2(10); // Use overloaded operator + MyClass result = obj1 + obj2; // Output result cout << "Result: " << result.getValue() << endl; return 0; } OutputResult: 15 To know more about operator overloading, refer to the article - Operator Overloading in C++ Comment More infoAdvertise with us Next Article How to Overload the (+) Plus Operator in C++? anuragvbj79 Follow Improve Article Tags : C++ Programs C++ cpp-operator CPP-OOPs CPP Examples +1 More Practice Tags : CPPcpp-operator Similar Reads How to Overload the Less-Than (<) Operator in C++?

In C++, operator overloading allows the user to redefine the behavior of an operator for a class. Overloading the function call operator () allows you to treat objects like functions enabling them to be called as if they were functions. Such classes are called functors in C++.
