C# Number Pattern 41

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;
      int m = 1;
      for (i = 1; i <= 9; i += 2) {
        for (j = i; j < 9; j++)
          Console.Write("  ");
        for (k = 1; k <= i; k++) {
          Console.Write("{0, 4}", m * m);
          m++;
        }
        Console.WriteLine();
      }
    }
  }
}

💻 Testing the Program

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

Output

        1
    4   9  16
25  36  49  64  81
100 121 144 169 196 225 256
289 324 361 400 441 484 529 576 625

🧠 How the Program Works

Let's break down the logic behind the code:

The program begins with the using System; statement, which includes the System namespace, allowing access to basic system-level functionality.
The program defines a new namespace called myApp using namespace myApp { ... }. Namespaces help organize code and prevent naming conflicts.
Inside the myApp namespace, there is a class Program. This is the main class of the program, and it contains the Main method, which is the entry point of the program.
The Main method is defined as follows: static void Main(string[] args) { ... }. It takes an array of strings as input (command-line arguments) but in this program, the arguments are not used.
Inside the Main method, three integer variables i, j, and k are declared. Additionally, an integer variable m is declared and initialized to 1.
The program enters a for loop that starts with i=1, runs as long as i is less than or equal to 9, and increments i by 2 in each iteration (i+=2). This loop is responsible for controlling the rows of the pattern to be printed.
Within the first for loop, there are two more nested for loops and one Console.WriteLine().
1. The first nested for loop (for(j=i; j<9; j++)) is responsible for printing spaces to format the output. It starts with j equal to the current value of i and runs until j is less than 9. In each iteration, it prints two spaces using Console.Write(" ").
2. After the first nested for loop, there is a second nested for loop (for(k=1; k<=i; k++)). This loop is responsible for printing the square of m in a specific format. It runs i times (since k goes from 1 to i) and prints the square of the current value of m using Console.Write("{0, 4}", m*m). The format "{0, 4}" ensures that the numbers are right-aligned with a width of 4 characters.
3. Inside the second nested for loop, the value of m is incremented (m++) to get the next value for the next iteration.
4. After both nested for loops, a new line is printed using Console.WriteLine();. This moves the cursor to the next line, so the next row of the pattern is printed on a new line.
The outer for loop continues to the next iteration, incrementing i by 2, and the whole process (nested loops and printing) is repeated until i is no longer less than or equal to 9.
Once the for loops are finished, the Main method exits, 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.
