C++ has the ability to provide the operators with a special meaning for a data type, this ability is known as operator overloading. Operator overloading is a compile-time polymorphism. For example, we can overload an operator ‘+’ in a class like String so that we can concatenate two strings by just using +. Other example classes where arithmetic operators may be overloaded are Complex Numbers, Fractional Numbers, Big integers, etc....

Difference between Operator Functions and Normal Functions

C++ // C++ Program to Demonstrate // Operator Overloading #include using namespace std;   class Complex { private:     int real, imag;   public:     Complex(int r = 0, int i = 0)     {         real = r;         imag = i;     }       // This is automatically called when '+' is used with     // between two Complex objects     Complex operator+(Complex const& obj)     {         Complex res;         res.real = real + obj.real;         res.imag = imag + obj.imag;         return res;     }     void print() { cout << real << " + i" << imag << '\n'; } };   int main() {     Complex c1(10, 5), c2(2, 4);     Complex c3 = c1 + c2;     c3.print(); }...
