25) Write a program to input a number and check whether it is Pronic ( heteromecic ) Number or not?(which is the product of two consecutive integers, that is, n*(n+1) , 110,k=(int) Math.sqrt (110), k*(k+1)=110
import java.util.*;
public class pronic_number
{
public static void main(String args[ ])
{
Scanner sc = new Scanner (System.in);
System.out.println("Enter a number");
int a = sc.nextInt();
int c = (int)Math.sqrt(a);
int d = c*(c+1);
if(d==a)
{
System.out.println(a+" is a PRONIC number");
}
else
{
System.out.println(a+" is not a PRONIC number");
}
}
}
