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

Write a C++ program to print a pattern in which the highest number of columns appears in the first row.

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

    // Display message asking for input
    cout << "\n\n Display the pattern like highest numbers of columns appear in first row:\n";
    cout << "------------------------------------------------------------------------------\n";
    cout << " Input the number of rows: ";
    cin >> n; // Read input for the number of rows from the user

    for (i = 1; i <= n;) // Loop for the number of rows
    {
        cout << i; // Print the current value of 'i'

        for (j = i + 1; j <= n;) // Loop to print the numbers after 'i'
        {
            cout << j; // Print the number
            j = j + 1; // Increment 'j'
        }

        cout << endl; // Move to the next line after each row is printed
        i = i + 1; // Increment 'i' for the next row
    }
}

Sample Output:

 Display the pattern like highest numbers of columns appear in first row:                                                                    
------------------------------------------------------------------------------                                                                
 Input the number of rows: 5                                           
12345                                                                  
2345                                                                   
345                                                                    
45
