C++ Exercises: Display the pattern using digits with right justified and the highest columns appears in first row

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

Write a C++ program that displays the pattern with the highest columns in the first row and digits with the right justified digits.

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; // Declare integer variables i, j, and rows

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

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

        for (j = 1; j <= i; j++) // Loop to print digits in ascending order
            cout << j; // Print the digits

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

Sample Output:

 Display the pattern using digits with right justified:                
-----------------------------------------------------------            
 Input number of rows: 5                                               
12345                                                                  
 1234                                                                  
  123                                                                  
   12
