C program to check the given number is Adam’s number

C program to check the given number is Adam’s number: Adam number is a number when reversed, the square of the number and the square of the reversed number should be numbers which are reverse of each other.

Input : 12

Explanation: Square of 12 = 144

Reverse of 12 = 21

Square of 21 = 441

Now Square of 12 and square of reverse of 12 are reverse of each other. Therefore 12 is Adam number.

Code for C program to check the given number is Adam’s number

#include<stdio.h>
#include<conio.h>
void main()
{
int reverse(int);
int square(int);
int n,n1,n2,sn,sn1,rsn1;
scanf("%d",&n);
n1=reverse(n);
n2=reverse(n1);
sn=square(n2);
sn1=square(n1);
rsn1=reverse(sn1);
if(n2==n && sn==rsn1)
 printf("It is an Adam’s number");
else
 printf("It is not an Adam’s number");
 }
int reverse(int n)
{
int rev=0,a;
 while(n>0)
 {
a=n%10;
rev=rev*10+a;
n=n/10;
 }
return rev;
 }
int square(int sn)
{
int s=sn*sn;
return s;
}
