Operator Overloading in C++
Operator Overloading in C++
In C++, Operator overloading is a compile-time polymorphism. It is an idea of giving special meaning to an existing operator in C++ without changing its original meaning . 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 the method by which we can change the function of some specific operators to do some different tasks .
CODE :
#include <iostream>
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();}12 + i9
