C++ Exercises: Display the pattern like right angle triangle using number which will repeat the number for that row

C++ For Loop: Exercise-37 with Solution

Write a C++ program that makes a pattern such as a right angle triangle using numbers that repeat.

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 number repeating for a row:\n";
    cout << "----------------------------------------------------------\n";
    cout << " Input number of rows: ";
    cin >> rows; // Read input for the number of rows from the user

    // Loop to print the pattern using repeated numbers for each row
    for (i = 1; i <= rows; i++) // Loop for the number of rows
    {
        for (j = 1; j <= i; j++) // Nested loop for printing numbers in each row
        {
            cout << i; // Print the value of 'i' (repeating numbers in each row)
        }
        cout << endl; // Move to the next line after each row is printed
    }
}

Sample Output:

 Display the pattern using number repeating for a row:                 
----------------------------------------------------------            
 Input number of rows: 5                                               
1

333                                                               
4444
