# To write a program and check whether it is a automorphic number or not

2
In mathematics, an automorphic number is a number whose square "ends"in the same digits as the number itself. For example 5×5=25,6×6=36 and 76×76=5776 so, 5,6 and 7 are all automorphic numbers. I hope this is OK for you plz mark me as brainlist

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

import java.util.*;

public class BrainlyPromoter

{

public static void chapter()

{

Scanner tp=new Scanner(System.in);

System.out.println("Enter a number that you want to check if its automorphic or not.");

int n=tp.nextInt();

int square=0, b=0, ct=1;

square=n*n;

int d=n;

int l=n;

while(n!=0)

{

b++;

n=n/10;

}

for(int k=1;k<=b;k++)

{

ct=ct*10;

}

int dig=square%ct;

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.

Entered number is an automorphic number.
