    'Sorting' algorithm

    #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 ->";
    		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];
    				biggest = arguments[i];
    	cout << "The Biggest number was: " << biggest;
    	int stop;
    	return 0;
    There's a small problem with this sorting algorithm i dished up, based somewhat on bubblesort, although it doesn't work..

    Use the quick sort...its much faster.

    so, your basing how many times you are going to loop on the value of arguments[i-1] ?

    for (i=num-1 ; i>0; i--)
    for (int j=0; j<i; j++)

    > if (arguments[j] > arguments[i])
    At this point, you need to be swapping these two values, not just remembering which one is biggest.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
