     sort(ar);

     printf("\nsorted array\n");

          printf("\t%d",ar[i]);

     getch();

}

void sort(int *p)

{

     int i,j,tmp;

     for(i=0;i<5;i++)

     {

          for(j=0;j<5-i-1;j++)

          {

              if(p[j]>p[j+1])

              {

                   tmp=p[j];

                   p[j]=p[j+1];
