Question

write a program in java to check if the number entered by user is automorpic .( automorphic no. is the number which is contained in the last digit(s) of its square)

Answer 1

class program
{
public static void main ( int n)
{
int i, c=o,m=n;
for (i=m ; m>0 ; m/=10)
c+=1;
if (n%1000 == n)
System.out.println(" automorphic number");
else
System.out.println (" not an automorphic no. ");
}
}

Answer 2

Sample program to check whether the number entered by user is automorphic:

import java.util.Scanner;

public class Brainly

{

   static void ct()

   {

       Scanner pt=new Scanner(System.in);

       System.out.println("Enter a number that you want to check if its automorphic.");

       int num=pt.nextInt();

       int sqr=0, b=0, c=1;

       sqr=num*num;

       int d=num;

       int l=num;

       while(num!=0)

       {

           b++;

           num=num/10;

       }

       for(int k=1;k<=b;k++)

       {

           c=c*10;

       }

       int dig=sqr%c;

       if(dig==d)

       {

           System.out.println("Entered number is an automorphic number.");

       }

       else    System.out.println("Entered number is not an automorphic number.");

   }

}

Output:

Enter a number that you want to check if its automorphic.
