The Program in C++ Program to find Pronic Number between 1 to 1000 is given below:

#include <iostream>
#include <cmath>

using namespace std;

bool isPronicNumber(int n) {
    for (int i = 1; i <= sqrt(n); i++) {
        if (i * (i + 1) == n) {
            return true;
        }
    }
    return false;
}

int main() {
    cout << "Hello Codeauri Family, the Pronic numbers between 1 and 1000 are: ";
    for (int i = 1; i <= 1000; i++) {
        if (isPronicNumber(i)) {
            cout << i << " ";
        }
    }
    cout << endl;
    return 0;
}

Output:

Hello Codeauri Family, the Pronic numbers between 1 and 1000 are: 2 6 12 20 30 42 56 72 90 110 132 156 182 210 240 272 306 342 380 420 462 506 552 600 650 702 756 812 870 930 992

Pro-Tips💡

This program implements a function isPronicNumber to check if a number is a Pronic number.

A Pronic number is a number that can be represented as the product of two consecutive integers.

The isPronicNumber function uses a loop to check if any two consecutive integers can produce the number.

If a pair is found, the function returns true, otherwise it returns false.

The main function loops through all numbers between 1 and 1000 and calls the isPronicNumber function for each number.

If the function returns true, the number is a Pronic number and is printed.

The output is a list of all Pronic numbers between 1 and 1000.
