post increment inside a loop?

[brendan89]

So I have the following code I am trying to understand regarding a quicksorting algorithm:

int end = array.length-1;
int start = 0;
int endOfList = start;
for(int read = start + 1; read<=end; read++)
		{
			if(array[read] < pivotValue)
			{
				endOfList++;
				switch(array, read, endOfList);
			}
	        }
switch(array, start, endOfList);

Now my question:
I don't see why we need to call the switch method inside the if...could somebody please explain to me what it does and why it's needed?

Thanks!

Can you provide the whole code with the main method so I can understand what you are trying to do?

I figured it out last night :) thanks though. Seems like the endoflist gets incremented whenever there is a lower value than the pivot and not incremented when there isn't. The swap at the end puts the pivot back into its correct place in the array. :D
