What is operator overloading?

Answer»

Operator Overloading is a very essential element to perform the operations on user-defined data types. By operator overloading we can modify the default meaning to the operators like +, -, *, /, <=, ETC. 

For example -

The FOLLOWING code is for adding two complex number USING operator overloading-

class complex{PRIVATE: float r, i;public: complex(float r, float i){ this->r=r; this->i=i; } complex(){} void displaydata(){ cout<<”real part = “<<r<<endl; cout<<”imaginary part = “<<i<<endl; } complex operator+(complex c){ return complex(r+c.r, i+c.i); }};int main(){complex a(2,3);complex b(3,4);complex c=a+b;c.displaydata();return 0;}
