C# Number Pattern 59

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;
      int k = 6, l = 13, m = 16;
      for (i = 1; i <= 5; i++) {
        for (j = 1; j <= 5; j++) {
          if (i == 1)
            Console.Write("{0, 3}", j);
          else if (j == 5)
            Console.Write("{0, 3}", k++);
          else if (i == 5)
            Console.Write("{0, 3}", l--);
          else if (j == 1)
            Console.Write("{0, 3}", m--);
          else
            Console.Write("   ");
        }
        Console.WriteLine();
      }
    }
  }
}

💻 Testing the Program

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

Output

1  2  3  4  5
16          6
15          7
14          8
13 12 11 10 9

🧠 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.
The namespace myApp block encloses the program's code within a namespace called "myApp." Namespaces help organize code and prevent naming conflicts.
The class Program block defines a class named "Program." This class contains the Main method, which is the entry point of the program.
Inside the Main method, the program declares three integer variables: i, j, k, l, and m.
- i and j are loop control variables for the nested for loops.
- k, l, and m are initialized with the values 6, 13, and 16, respectively.
The program starts a nested for loop with the outer loop controlled by the variable i and the inner loop controlled by the variable j.
- The outer loop runs from i=1 to i<=5.
- The inner loop runs from j=1 to j<=5.
Inside the nested for loop, there are several if-else conditions to determine what to print for each position in the grid.
For the first row (i == 1), it prints the values 1 to 5 for the columns:
- It uses Console.Write("{0, 3}", j); to print the value of j with three characters of width, right-aligned.
For the last column (j == 5) in each row, it prints the values 6 and onwards using the variable k:
- It uses Console.Write("{0, 3}", k++); to print the value of k with three characters of width, right-aligned.
- The k variable is then incremented after each print.
For the last row (i == 5), it prints the values 13 to 9 for the columns:
- It uses Console.Write("{0, 3}", l--); to print the value of l with three characters of width, right-aligned.
- The l variable is then decremented after each print.
For the first column (j == 1) in each row, it prints the values 16 to 12 using the variable m:
- It uses Console.Write("{0, 3}", m--); to print the value of m with three characters of width, right-aligned.
- The m variable is then decremented after each print.
If none of the above conditions are met, it means the current position is inside the grid, but not on the boundary. In this case, it prints three spaces to create a space in the grid.
After printing each row, it moves to the next line using Console.WriteLine();.
The program continues the outer loop for the next row until all rows are printed.
Once the outer loop is done (i reaches 6), the program exits the Main method, and the program execution 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.
