Quick Sort in c programming........

Quick Sort :

#include<stdio.h>

#include<conio.h>

int no;

void quicksort(int low,int high,int a[])

{

int i,down=low,up=high,pivot;

pivot=a[down];

down++;

if(low<high)

{

while(down<=up)

{

while(pivot>a[down])

   down++;

while(pivot<a[up])

   up--;

if(down<up)

{

   a[down]=a[down]+a[up];

   a[up]=a[down]-a[up];

   a[down]=a[down]-a[up];

}

}

a[low]=a[up];

a[up]=pivot;

printf("\nArray Status:");

for(i=0;i<no;printf("-->%d ",*(a+i)),i++);

quicksort(low,up-1,a);

quicksort(up+1,high,a);

}

else

return;

}

void main()

{

int *a;

int n,i;

printf("Enter the size of the array:");

scanf("%d",&n);

no=n;

a=(int *)malloc(sizeof(int)*n);

for(i=0;i<n;scanf("%d",(a+i)),i++);

quicksort(0,n-1,a);

printf("\nSorted List:");

for(i=0;i<n;printf(" %d",*(a+i)),i++);

getch();

}

Copy and paste it in a notepad...then save it in "tc\bin" as "name.c" and open the program in turbo c compiler "by file->open->name.c"
