When binary operators are overloaded, the left hand object must be an object of the relevant class #include<iostream> using namespace std; class complex { int real,img; public: void read() cout<<"\nEnter the REAL PART : "; cin>>real; cout<<"\nEnter the IMAGINARY PART : "; cin>>img; complex operator +(complex c2) complex c3; c3.real=real+c2.real; c3.img=img+c2.img; return c3; void display() { cout<<real<<"+"<<img<<"i"; } }; int main() complex c1,c2,c3; int choice, cont; cout<<"\n\nEnter the First Complex Number"; c1.read(); cout<<"\n\nEnter the Second Complex Number"; c2.read(); c3=c1+c2; // binary + overloaded cout<<"\n\nSUM = "; c3.display(); return ; Output
