'Sorting' algorithm

[Dual-Catfish]

#include <iostream.h>
int main()
{
	int num;	
	cout << "Hey buddy how many numbers do you wanto enter?";
	cin >> num;
	cout << "\n";
	float biggest;

	float *arguments = new float[num];
	
	for (int i=0; i<num; i++)
	{
		cout << "Enter some numbers from my crazy algorithm to sort ->";
		cin>>arguments[i];
		cout << "\n";
	}
	for (i=arguments[i-1]; i>0; i--)
	{
		for (int j=0; j<num; j++)
		{
			if (arguments[j] > arguments[i])
			{
				biggest = arguments[j];
			}
			else
			{
				biggest = arguments[i];
			}
		}
	}
	cout << "The Biggest number was: " << biggest;
	int stop;
	cin>>stop;

	return 0;
}

There's a small problem with this sorting algorithm i dished up, based somewhat on bubblesort, although it doesn't work..
