Static Variable problem

[and kand 97]

I have this assignment for school. Here's what I have so far. Can anyone tell me if I'm on the right track?

  int pb(){

	static double unit = 2;
	




}




int main(){
	double x,y;
 	
	
	do {
		
		cout << "Enter a size and price" <<endl;
		cin>>x,y;
		if ( x/y < pb() ) {
			cout<< x/y <<endl;
 		}
		
	} while (x != 0 || y !=0);
	
	
	
	return 0;


}

What is the program supposed to do?

[anup30]

#include <iostream>
using namespace std;

double pb(double arg)
{
	static double unit = 999999999;
	
	if(arg<unit && arg!=0)
	{
		unit = arg;		
	}
	
		
	return unit;
}


int main(){
	double ounce, price;
	
	while (true )
	{		
		cout << "Enter a size and price" <<endl;
		cin >> ounce >> price;

		if(ounce==0 || price==0) break;
		double m = price/ounce;
		cout << "\n lowest price: "<< pb(m) << "\n\n";		
	}

	return 0;
}
