Optimised!! :-) some extra condition added to avoid printing repeated numbers.

#include<stdio.h>
void dev(int n,int i)
{
if(n <= i) return;
while(i <= n){
if((n % i) == 0){
if(n!=i) printf("%d ",i);
printf("%d ",n/i);
break;
}
i++;
}
dev(n/i,i+1);
return;
}
main()
{
int n;

printf("Enter number:");
scanf("%d",&n);

dev(n,2);
printf("\n");
return 0;
}

Given only putchar (no sprintf, itoa, etc.) write a routine putlong that prints out an unsigned long in decimal. [ I gave the obvious solution of taking % 10 and / 10, which gives us the decimal value in reverse order. This requires an array since we need to print it out in the correct order. The interviewer wasn't too pleased and asked me to give a solution which didn't need the array ].
