since it is given as digits, lets assume that we take only
integers.

#include<stdio.h>
#include<conio.h>
void main()
{
int n,a[20],count=0;
printf("enter th number :");
scanf("%d",&n);
for(int i=0;n>0;i++)
{
a[i]=n%10;
n=n/10;
count++;
}
for(i=0;i<count;i++)
{
printf("%c",a[i]);
}
getch();
}
this will be the logic , i think so.....!
