    Question Bubble Sort, Qucik Sort

    I need to write a program that time a bubble sort and quick sort (sorting 50,000 characters). I have the Bubble sort in the book I have but I don't have the quick sort. Does anyone know where I can find this online or a book I could reference.

    Thanks...

    example for qsort()
    Code:
    /* qsort example */
    #include <stdio.h>
    #include <stdlib.h>
    
    int compare (const void * a, const void * b)
    {
      return ( *(int*)a - *(int*)b );
    }
    
    int main ()
    {
      int values[] = { 40, 10, 100, 90, 20, 25 };
      int * pItem;
      int n;
      qsort (values, 6, sizeof(int), compare);
      for (n=0; n<6; n++)
      {
        printf ("%d ",values[n]);
      }
      return 0;
    }

    "where I can find this online" is a classic question which will always get you an answer of "have you tried searching?"

    http://cboard.cprogramming.com/search.php
    www.google.com

    When all else fails, read the instructions.
    If you're posting code, use code tags: [code] /* insert code here */ [/code]
