void putlong(unsigned long x)
{ if (x > 10) putlong(x / 10);
putchar(x % 10+'0');
}
main()
{
long int a;
printf("enter long integer:");
scanf("%d",&a);
putlong(a);
return 0;

}

Answer / cmos

This can be done by recursion.
Since the number of recursive calls is not significant, it does not affect the performance much

printnumber(int i)
{
if(i == 0)
return;
printnumber(i/10);
putchar(’0′ + i%10);
}

main() { printf("\nab"); printf("\bsi"); printf("\rha"); }
