1.	Write a program to input a number and check and print whether it is a Pronic number [15] or not. (Pronic number is the number which is the product of two consecutive integers) Examples : 12 = 3 × 4 . 20 = 4 × 5 42 = 6 × 7
Answer» import java.io.; import java.util. Scanner; class Pronic] public static void main(String argsQ) throws IOException { Scanner sc = new Scanner(System.in); System.out.print(“Enter the number: “); int n = sc.nextlnt(); int i = 0; while(i (i + 1) < n){ i++; } if(i *(i + 1) = = n){ System.out.println(n + ” is a Pronic Number.”); } else { System.out.prindn(n + ” is not a Pronic Number.”); } } }

import java.io.*;

import java.util. Scanner; class Pronic]

public static void main(String argsQ) throws IOException {

Scanner sc = new Scanner(System.in); System.out.print(“Enter the number: “);

int n = sc.nextlnt();

int i = 0;

while(i * (i + 1) < n){

i++;

}

if(i *(i + 1) = = n){

System.out.println(n + ” is a Pronic Number.”);

}

else {

System.out.prindn(n + ” is not a Pronic Number.”);

}
