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

C++ For Loop: Exercise-53 with Solution

Write a C++ program to display the pattern like right angle triangle with right justified digits.

Pictorial Presentation:

Sample Solution:

C++ Code :

#include <iostream>
using namespace std;

int main()
{
    int i, j, rows, d;
    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;
    for (i = 1; i <= rows; i++) 
    {
        for (j = 1; j <= rows - i; j++) 
        {
            cout << " ";
        }
        d = i;
        for (j = 1; j <= i; j++) 
        {
            cout << d;
            d--;
        }
        cout << endl;
    }
}

Sample Output:

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