The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Convert c code into assembly code

Asked by tjodolf in Assembly Programming Language

Tags: c, convert, assembly, code

Hey. I hope you can help me with converting some c code into assembly code, i have tried much now, and i still don't get it. What would help me alot, would be some comments for each line in the assembly code, so i better can understand to convert process...

Here is the code:

/* Standard quicksort. */
void quicksort(int a[], int left, int right)
{
      int lp = left - 1;
      int rp = right;
      int v = a[right]; /* the partioning element */

      if (right <= left)
            /* Array has one or null elements to sort */
            return;

      /* No elements to the left of lp are greater than the partioning elemnt. */
      while (1) {
            while (a[++lp] < v)
                  ;

            while (v < a[--rp])
                  /* In case the partioning element is the smallest in the array */
                  if (rp == left)
                        break;

            if (lp >= rp)
                  break;

            /* Deadlock, switch elements and continue */
            swap(&a[lp], &a[rp]);
      }
      /* This completes the partioning */
      swap(&a[lp], &a[right]);

      /* Now every element to the left of a[lp] are smaller than a[lp],
       * and every element to the right is larger. */

      quicksort(a, left, lp - 1);
      quicksort(a, lp + 1, right);
}

static void swap(int *x, int *y)
{
      int temp = *x;
      *x = *y;
      *y = temp;
}

Hope you can help.

Terje.
