class Gamma

{

int x,y,z;

public:

void getdata(int a, int b,int c)

}

void operator*()

{

}

};

void main()

{

clrscr();

cout<<"Operator overloading program: ";

Gamma G;

G.getdata(10,25,30);

cout<< "\n G= ";

G.show();

*G;

cout<<"\n after applying operator(*) function square values ";

cout<< "\n G= ";

}

output:

Operator overloading program:

G= 10 25 30

after applying operator(*) function square values

G= 100 625 900
