Solve Pronic Number Program

Find if a given number is Pronic number or not.

Pronic Number: it is the product of two consecutive integers, n(n+1).

e.g 56= 7 x 8 .

import java.util.Scanner;
public class PronicNum
{
   public static void main(String[] args) 
   {
      System.out.println("Enter the number:");
      Scanner sc = new Scanner(System.in);
      int n = sc.nextInt();
      int fact = 0; 
      for(int i = 1; i < n; i++) 
      {
         if (n % i == 0)
            if (i * (i + 1) == n) 
               fact = i;
      }
      if (fact != 0) 
         System.out.println("Yes");
      else
         System.out.println("No");
   }
