Hello Learners , Today we will code for Quick Sort programming using Array in C Programming.

 

 

#include<stdio.h>

void quicksort(int [10],int,int);

int main()
{
int x[20],size,i;

printf(“Enter size of the array: “);
scanf(“%d”,&size);

printf(“Enter %d elements: “,size);
for(i=0;i<size;i++)
scanf(“%d”,&x[i]);

quicksort(x,0,size-1);

printf(“Sorted elements: “);
for(i=0;i<size;i++)
printf(” %d”,x[i]);

return 0;
}
void quicksort(int x[10],int first,int last)
{
int pivot,j,temp,i;

if(first<last)
{
pivot=first;
i=first;
j=last;

while(i<j)
{
while(x[i]<=x[pivot]&&i<last)
i++;
while(x[j]>x[pivot])
j–;
if(i<j)
{
temp=x[i];
x[i]=x[j];
x[j]=temp;
}
}

temp=x[pivot];
x[pivot]=x[j];
x[j]=temp;
quicksort(x,first,j-1);
quicksort(x,j+1,last);

}
}

Happy Coding, Keep Coding
