C# Number Pattern 21

Here`s a program that prints the above number pattern using C# Programming:

example.cs

Copied

using System;

namespace myApp {
  class Program {
    static void Main(string[] args) {
      int i, j, k, m;
      for (i = 1; i <= 5; i++) {
        Console.Write(i + " ");
        m = 4;
        k = i + m;
        for (j = 1; j < i; j++) {
          Console.Write(k + " ");
          m--;
          k = k + m;
        }
        Console.WriteLine();
      }
    }
  }
}

💻 Testing the Program

When you run the above program, it will print the following output:

Output

1
2 6
3 7 10
4 8 11 13 
5 9 12 14 15

🧠 How the Program Works

Let's break down the logic behind the code:

The program starts with the using System; statement, which indicates that the program will use functionalities from the System namespace, including the Console class.
The program defines a new namespace called myApp using namespace myApp { ... }. Namespaces are used to organize code and prevent naming conflicts.
Inside the myApp namespace, there's a class called Program, which contains the Main method. The Main method is the entry point of the program and is called when the program starts.
The Main method begins with the following variable declarations:
- int i, j, k, m;: These variables will be used in the following loops to control the flow and store intermediate values.
The first for loop: for(i=1; i<=5; i++) { ... }
- This loop iterates from i = 1 to i = 5 (inclusive).
- i is initialized to 1, and the loop executes as long as i is less than or equal to 5.
- After each iteration, i is incremented by 1.
Inside the first for loop, the program executes the following steps:
- Console.Write(i + " ");: This line writes the value of i followed by a space to the console. It prints the current value of i on the same line.
- m = 4;: m is set to 4 in each iteration of the outer loop.
- k = i + m;: k is set to the sum of i and m. Since m is initially 4 and i is the loop counter, k starts with the value i + 4.
The second for loop: for(j=1; j<i; j++) { ... }
- This loop iterates from j = 1 to j = i - 1.
- j is initialized to 1, and the loop executes as long as j is less than i.
- After each iteration, j is incremented by 1.
Inside the second for loop, the program executes the following steps:
- Console.Write(k + " ");: This line writes the value of k followed by a space to the console. It prints the current value of k on the same line.
- m--;: Decrements the value of m by 1.
- k = k + m;: Updates the value of k by adding the current value of m.
After the second for loop finishes, the program executes Console.WriteLine();, which moves the cursor to the next line, creating a new line.
The first for loop continues with the next iteration, repeating the process until i becomes 6.
Once the first for loop is completed, the Main method finishes execution, and the program ends.

💯 Tips for Enhancement:

Explore the versatility of this pattern by adjusting its parameters. Whether you increase or decrease the size, tweak the spacing, or modify the characters used, each change opens up a world of possibilities, allowing you to customize and create your unique visual effects.
