get() function or show() function ?!

[shahin007]

Hi,
can i use get_xy() function in this program instead of show() function?
if so, what is the difference?
which one is better and why?
void showxy() {cout<< x << " ' " << y << endl;}

void get_xy(int &i,int &j) {i=x;j=y;}
full program code:

#include <iostream>
using namespace std;
class coord
{
	int x,y;
public:
	coord () {x=0 ; y=0;}
	coord (int i,int j) {x=i;y=j;}
	void showxy() {cout<< x  << " ' " << y << endl;}
	coord operator +(coord ob)
	{
		coord temp;
		temp.x = x + ob.x;
		temp.y = y + ob.y;
		return temp;
	}
	coord operator -(coord ob)
	{
		coord temp;
		temp.x = x - ob.x;
		temp.y = y - ob.y;
		return temp;
	}
	coord operator =(coord ob)
	{
		x = ob.x;
		y = ob.y;
		return *this;
	}
};
int main()
{
	coord ob1(10,10),ob2(5,3),ob3;
	ob3=ob1+ob2;
	ob3.showxy();
	ob3=ob1-ob2;
	ob3.showxy();
	ob3=ob2;
	ob3.showxy();
}
