C program to remove even numbers and fill it with zero
Input array 1,2,3,4,5,6
Output 1,3,5,0,0,0

#include<stdio.h>
void main()

int i,j,k,n=6,a[]={1,2,3,4,5,6};
clrscr();
for(i=0;i<n;i++)
{
if(a[i]%2==0)
{
a[i]=-1;
}
else
printf("%d",a[i]);
}
for(i=0;i<n;i++)
{
if(a[i]==-1)
printf("0");
 }
getch();
}

Can you do the loop step 2? Would be more efficient.

You say it will remove the even numbers and zero fill, but it doesn't. At the start the array looks like this:
{1,2,3,4,5,6}
and at the end it looks like this:
{1,-1,3,-1,5,-1}

Even numbers not removed (but instead replaced with -1), array not zero-filled. The program does not do what it is supposed to.

but at last the expected output getting..

If that's all that matters, here's the programme in a much more efficient form:

#include <stdio.h>

int main()
{
  printf("1 3 5 0 0 0");
}

As it is, this is a ZOHO interview question, as seen here:
https://www.daniweb.com/software-development/c/threads/456728/zoho-interview-question
and they certainly wouldn't accept an answer that didn't actually do what it was supposed to, but instead output something to make the user think it was working.
