Write a program in C++ to check whether a number is a Pronic Number or Heteromecic Number or not.

Sample Solution:

C++ Code :

#include<bits/stdc++.h> // Include necessary libraries
using namespace std; // Use the standard namespace

int main()
{
    int prno, i, n, flg; // Declare variables

    cout << "\n\n Check whether a number is a Pronic Number or Heteromecic Number or not: \n"; // Display a message
    cout << " ----------------------------------------------------------------------------\n";
    cout << " Input a number: "; // Prompt the user to input a number
    cin >> prno; // Read the input number

    // Loop to check if the given number is a Pronic Number
    for (i = 1; i <= prno; i++)
    {
        if (i * (i + 1) == prno) // Check if the number is a product of consecutive integers
        {
            flg = 1; // Set flag to 1 if it is a Pronic Number
            break; // Exit the loop if a Pronic Number is found
        }
    }

    // Check if the flag is set, indicating that the number is a Pronic Number
    if (flg == 1)
    {
        cout << " The given number is a Pronic Number." << endl; // Display if the number is a Pronic Number
    }
    else
    {
        cout << " The given number is not a Pronic Number." << endl; // Display if the number is not a Pronic Number
    }

    return 0; // Return 0 to indicate successful execution
}

Sample Output:

Check whether a number is a Pronic Number or Heteromecic Number or not:                             
 ----------------------------------------------------------------------------                        
 Input a number: 42                                                                                  
 The given number is a Pronic Number
