class unary

{

int x,y,z;

public:

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

void display(void);

void operator -();

};

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

{

x=a;

y=b;

z=c;

}

void unary::display(void)

{

cout<<x<<" "<<y<<" "<<z<<"\n";

}

void unary::operator -()

{

x=-x;

y=-y;

z=-z;

}

int main()

{

unary u;

u.getdata(20,-30,40);

cout<<"u:";
