﻿ C# - Pattern like right angle triangle using a number

# C#: Display the pattern like right angle triangle using a number

## C# Sharp For Loop: Exercise-10 with Solution

Write a program in C# Sharp to display a pattern like a right angle triangle with a number.

Sample Output:

```1
12
123
1234
```

Sample Solution:-

C# Sharp Code:

``````using System;  // Importing necessary namespace

public class Exercise10  // Declaration of the Exercise10 class
{
public static void Main()  // Main method, entry point of the program
{
int i, j, rows;  // Declaration of variables 'i', 'j' for iteration, 'rows' to store the number of rows

Console.Write("\n\n");  // Displaying new lines
Console.Write("Display the pattern as a right-angle triangle using numbers:\n");  // Displaying the purpose of the program
Console.Write("-----------------------------------------------------------");  // Displaying a separator
Console.Write("\n\n");

Console.Write("Input number of rows : ");  // Prompting the user to input the number of rows

for (i = 1; i <= rows; i++)  // Loop to iterate through each row
{
for (j = 1; j <= i; j++)  // Loop to print numbers in each row from 1 to 'i'
{
Console.Write("{0}", j);  // Displaying numbers to form the pattern
}
Console.Write("\n");  // Moving to the next line to form the right-angled pattern
}
}
}
```
```

Sample Output:

```Display the pattern as right angle triangle using number:
-----------------------------------------------------------

Input number of rows : 10
1
12
123
1234
12345
123456
1234567
12345678
123456789
12345678910
```
