I feel as if my quicksort can be made more efficient, but what?
I don't like seeing arrays passed as parameters.

void quicksort(int list[], int low, int high)
//                  ^^^^^


Inside the function all similarity to an array has disappeared. It has decayed into a pointer. By using the array like syntax you might catch people out that want to treat it as an array (which is a real maintenance issue).

If this code is C then just pass as a pointer.
If this code is C++ then pass as a reference to an array, or use a container type and pass by reference (I prefer the container option as you can template it).

In quick pre-condition checks at the head of a function like this.
There is no need for the else part.

if(low &gt;= high)
    return;
else


It looks neater and saves you a level of indentation. 

One variable per line.
Also give the variables more meaningful names.

    int pivot = low, i = low, j = high;


Also I would say that pivot is really the value you are pivoting around. Not the location of the value you are pivoting around.

    int pivot = list[&lt;location Of Pivot Value&gt;]; // See below for more.


Pretty sure there is a bug here i &lt; high is not correct.

        while(list[i] &lt;= list[pivot] &amp;&amp; i &lt; high)


Same thing here. Pretty sure there is a bug here j &gt; low is not correct.

        while(list[j] &gt; list[pivot] &amp;&amp; j &gt; low)


Yep. You are correct the break is ugly here.

        if(i &lt; j)
        {    std::swap(list[i], list[j]);
        }


You are only doing this (below) to prevent your self choosing the same pivot point each time. So you should choose a different technique to choose the pivot point. Why not the element in the middle of the list?

    int temp = list[pivot];
    list[pivot] = list[j];
    list[j] = temp;


You pass the location of the first and last element in the array.

    quicksort(list, low, j-1);
    quicksort(list, j+1, high);


It is more C++ like to use first and one past the point you consider end. It also makes the code look neater try it and see.
