Introduction
This tutorial will help you to understand Pronic Number or Heteromecic Number Program. In-order to start writing any program we have to understand business requirement and what is the problem. As we know that Pronic Number or Heteromecic Number Program is a number which is the product of two consecutive integers, that is, a number of the form n(n + 1).
So we can say Tn = n*(n+1) where n is the number of term.
The first few pronic numbers are:
2, 6, 12, 20, 30, 42, 56, 72, 90, 110, 132, 156, 182, 210, 240, 272, 306, 342, 380, 420, 462 … etc.
Explanation:
First Term: 2 =1*2 = 2
Second Term: 6 = 2*3= 6

Flowchart
Please find sample flowchart diagram for this program as given below –
Program(Code) Using Java Language
package com.kw.sample;
import java.util.Scanner;
/**

public class KWPronicNumberExample {
public static void main(String args[]) {
// This helps to take number from keyboard
Scanner sc = new Scanner(System.in);
System.out.print("Enter a number : ");
int n = sc.nextInt();
Boolean flag = false;
// Check number against each term in the series
for (int i = 0; i < n; i++) {
if (i * (i + 1) == n) {
flag = true;
break;
}
}
if (flag) {
System.out.println(n + " is a Pronic Number.");
} else {
System.out.println(n + " is not a Pronic Number.");
}
}
}
Output
Scenario 1:
Enter a number : 10
10 is not a Pronic Number.
Scenario 2:
Enter a number : 6
6 is a Pronic Number.
Video Explanation
This video helps to understand flowchart and program which written in the above steps. There are various ways to write a program and we are not covering all of them as this is just for practice. Please post your program in the comment box so other can utilize it.
