C# Number Pattern 31

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;
      for (i = 1; i <= 5; i++) {
        for (j = 1; j < i * 2; j++) {
          if (j % 2 == 0)
            Console.Write("*");
          else
            Console.Write(i);
        }
        Console.WriteLine();
      }
      for (i = 4; i >= 1; i--) {
        for (j = 1; j < i * 2; j++) {
          if (j % 2 == 0)
            Console.Write("*");
          else
            Console.Write(i);
        }
        Console.WriteLine();
      }
    }
  }
}

💻 Testing the Program

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

Output

1
2*2
3*3*3
4*4*4*4
5*5*5*5*5
4*4*4*4
3*3*3
2*2
1

🧠 How the Program Works

Let's break down the logic behind the code:

The using System; statement includes the System namespace, which contains fundamental types and classes used in C# programming.
The program defines a namespace called myApp to organize the code.
Inside the myApp namespace, there is a class named Program, which contains the Main method. The Main method is the entry point of the program.
The Main method starts by declaring two integer variables i and j to be used as loop counters.
The first for loop is used to print the top half of the pattern. It runs from i=1 to i<=5, with i incrementing by 1 each iteration.
Inside the first for loop, there is another for loop nested within it, using j as the loop counter. It runs from j=1 to j<i*2, with j incrementing by 1 each iteration. This loop controls the number of characters to be printed on each line.
Within the nested for loop, there is an if-else statement. If j%2 == 0, it means j is an even number. In that case, a star (*) is printed using Console.Write("*"). Otherwise, if j is an odd number, the value of i is printed using Console.Write(i).
After printing the characters in the nested loop, Console.WriteLine(); is used to move to the next line to create the pattern.
The first for loop prints the top half of the pattern, which starts with a single digit and increases the number of characters on each line. It alternates between numbers and stars.
After the first for loop completes, there is a second for loop to print the bottom half of the pattern. This time, it runs from i=4 to i>=1, with i decrementing by 1 each iteration.
The second for loop is the same as the first one, and it prints the bottom half of the pattern, which starts with four digits and decreases the number of characters on each line. It also alternates between numbers and stars.
The program execution finishes, and the output is displayed on the console.

💯 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.
