C++ Exercises: Display the pattern like right angle triangle with right justified using digits

Sample Solution:

C++ Code :

#include <iostream> // Include the input/output stream library
using namespace std; // Using standard namespace

int main() // Main function where the execution of the program starts
{
    int i, j, rows, d; // Declare integer variables i, j, rows, and d

    // Display message asking for input
    cout << "\n\n Display the pattern like right angle triangle with right justified using digits:\n";
    cout << "-------------------------------------------------------------------------------------\n";
    cout << " Input number of rows: ";
    cin >> rows; // Read input for the number of rows from the user

    for (i = 1; i <= rows; i++) // Loop for the number of rows
    {
        for (j = 1; j <= rows - i; j++) // Loop to print spaces before the digits
        {
            cout << " "; // Print a space for formatting
        }

        d = i; // Assign the value of 'i' to 'd'

        for (j = 1; j <= i; j++) // Loop to print digits in descending order
        {
            cout << d; // Print the value of 'd'
            d--; // Decrement 'd' for the next digit
        }

        cout << endl; // Move to the next line after each row is printed
    }
}

Sample Output:

 Display the pattern like right angle triangle with right justified using digits:                                                             
-------------------------------------------------------------------------------------                                                         
 Input number of rows: 5                                               
    1                                                                  
   21                                                                  
  321                                                                  
 4321
