Complete the program below by writing the function largeDiv that finds the largest divisor of a number other than itself. (Hint: try half of the number first. Then as long as you haven't found a divisor, keep subtracting 1 from your trial value. You can be sure that 1 will divide the number if you don't find a larger divisor.)

#include 
using namespace std;

// Write your function prototype for largeDiv here.





int main()
{
	int number;
	int divisor;

	cout << "Enter an integer greater than 1 => ";
	cin >> number;

	divisor = largeDiv( number );

	if ( divisor == 1 )
	   cout << number << " is a prime number." << endl;
	else
	   cout << divisor << " is the largest divisor of " << number << endl;

	return 0;
}
