THIS IS D PROGRAM TO GENERATE LUCKY NUMBERS OUT OF A GIVEN NUMBERS

FIRSTLY SUPPOSE CONSIDER 10 ITEMS
1 2 3 4 5 6 7 8 9 10
FIRSTLY EACH 2ND ELEMENT IS DELETED THEN WE GET
1 3 5 7 9
THEN EACH 3RD ELEMENT IS DELETED
1 3 7 9
THEN EACH 4TH ELEMENT WILL BE DELETED THEN WE GET
1 3 7
NOW EACH 5TH ELEMENT IS DELETED AS THERE IS NO 5TH ITEM WE GET
1 3 7
THE ABOVE NOS
1 3 7
ARE CALLED LUCKY NOS

THIS GIVEN PROGRAM IS WRITTEN IN C SO TRY IT ONCE
CODE:C
Code:
```#include"stdio.h"
#include"conio.h"
void main()
{
int i,k=0,p=2,t=0,n;int a[100];
printf("enter the size of the array:\n");
scanf("%d",&n);
printf("enter the elements of the array\n");
for(i=0;i<n;i++)
{
scanf("%d",&a[i]);
}
printf(" The Sequence Of Lucky Nos Per Step Are:\n");
for(i=0;i<n;i++)
{
printf("%d",a[i]);
printf("\t");
}

while(1)
{
t=0;
for(i=0;i<n;i++)
{

if(a[i]!=32767)
{
k++;
if(k==p)
{
a[i]=32767;t++;
k=0;
}

}
}
p++;k=0;
if(t==0)
{
break;
}
printf("\n");
for(i=0;i<n;i++)
{
if(a[i]!=32767)
{
printf("%d ",a[i]);
printf("\t");
}
}
printf("\n");

}
getch();
