Last update on December 20 2024 12:23:22 (UTC/GMT +8 hours)

Write a C++ program to display the pattern using digits with left justified spacing and the highest columns appearing in the first row in descending order.

Visual Presentation:

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 using digits with left justified:\n";
    cout << "----------------------------------------------------------\n";
    cout << " Input number of rows: ";
    cin >> rows; // Read input for the number of rows from the user

    d = 0; // Initialize variable d to 0

    for (i = 1; i <= rows; i++) // Loop for the number of rows
	{
        for (j = rows - d; j >= 1; j--) // Loop to print digits in descending order
		{
            cout << j << " "; // Print the digit followed by a space
        }

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

Sample Output:

 Display the pattern using digits with left justified:                 
----------------------------------------------------------             
 Input number of rows: 5                                               
5 4 3 2 1                                                              
4 3 2 1                                                                
3 2 1                                                                  
2 1
