Sample Solution:-

C++ Code :

#include <iostream> // Including input-output stream header

using namespace std; // Using standard namespace to avoid writing std::

int main() // Start of the main function
{
    int i, sum = 0; // Declaration of integer variables 'i' (loop counter), 'sum' (stores the sum of numbers)

    cout << "\n\n Find the number and sum of all integers between 100 and 200, divisible by 9:\n"; // Displaying a message on the console
    cout << "--------------------------------------------------------------------------------\n";
    cout << " Numbers between 100 and 200, divisible by 9: " << endl; // Displaying a message indicating the range of numbers

    for (i = 101; i < 200; i++) // Loop to iterate through numbers between 101 and 199 (inclusive)
    {
        if (i % 9 == 0) // Checking if the number is divisible by 9
        {
            cout << " " << i; // Displaying the number if it is divisible by 9
            sum += i; // Adding the number to the sum
        }
    }

    cout << "\n The sum : " << sum << endl; // Displaying the sum of the numbers divisible by 9
}

Sample Output:

 Find the number and sum of all integer between 100 and 200, divisible by 9:                                                                  
--------------------------------------------------------------------------------                                                              
 Numbers between 100 and 200, divisible by 9:                          
 108 117 126 135 144 153 162 171 180 189 198                           
 The sum : 1683
