I tryed to make that exercice ( 7.3) for fun and I got 3 errors who I cannot solve.

THis is my code :

#include <iostream>

using namespace std;

int main()
{
	unsigned short small;
	unsigned short large;
	const unsigned short MAXSMALL=65535;

	cout<<"Enter a small number: ";
	cin >> small;
	cout<<"Enter a large number: ";
	cin >> large;
	cout<< "Your small number is : " <<small<<"...";

	while (small < large && large > 0 && small < MAXSMALL)
	{
		if (small % 5000 ==0)
			cout<<".";
		small++;
		large-=2;
	}

	cout << "\nSmall: " << small << "\nLarge: " << large <<endl;
	return 0;
}

This is the errors :
