Write a program in C++ to display a pattern like a right angle triangle using an asterisk.

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 like right angle triangle using an asterisk:\n";
    cout << "---------------------------------------------------------------------\n";
    cout << " Input number of rows: ";
    cin >> rows; // Read input for the number of rows from the user

    // Loop to print the right angle triangle pattern with asterisks
    for (i = 1; i <= rows; i++) // Loop for the number of rows
    {
        for (j = 1; j <= i; j++) // Nested loop for printing asterisks in each row
        {
            cout << "*"; // Print an asterisk
        }
        cout << endl; // Move to the next line after each row is printed
    }
}

Sample Output:

 display the pattern like right angle triangle using an asterisk:      
---------------------------------------------------------------------  
 Input number of rows: 5                                               
*                                                                      
**                                                                     
***                                                                    
****
