Step by Step solution about How to resolve the algorithm Loops/For step by step in the C# programming language

The provided C# code is a simple program that uses nested for loops to print a pyramid pattern of asterisks (*). Let's break down the code step by step to understand its functionality:

using System;
// The code begins by including the 'System' namespace, which provides fundamental C# types and functionality.

class Program {
   // The 'Program' class is defined as the entry point for the application.
   static void Main(string[] args)
   // Inside the 'Main' method, we have our program logic.
   {
       // The outer 'for' loop iterates from 'i = 0' to 'i < 5'. This loop controls the number of rows in our pyramid.
       for (int i = 0; i < 5; i++)
       {
           // The inner 'for' loop iterates from 'j = 0' to 'j <= i'. This loop controls the number of asterisks in each row.
           for (int j = 0; j <= i; j++)
           {
               // Inside the inner loop, we use 'Console.Write("*")' to print an asterisk.
               Console.Write("*");
           }
           // After each row of asterisks is printed, we move to the next line using 'Console.WriteLine()'.
           Console.WriteLine();
       }
   }
}

Explanation:

1. Outer Loop (Row Counter):

   • The outer loop (controlled by the variable i) iterates from i = 0 to i < 5. This means it will execute five times, creating five rows in our pyramid pattern.

2. Inner Loop (Asterisk Printer):

   • Inside each iteration of the outer loop, the inner loop (controlled by j) iterates from j = 0 to j <= i. The condition j <= i ensures that the number of asterisks printed in each row is always equal to the row number (i.e., the first row has 1 asterisk, the second row has 2 asterisks, and so on).

3. Printing Asterisks:

   • Inside the inner loop, the Console.Write("*") statement is used to print an asterisk (*) for each iteration. This gradually builds up the row of asterisks.

4. Newline:

   • After completing the inner loop for each row, the Console.WriteLine() statement is used to move to the next line, creating a new row for the next iteration of the outer loop.

5. Pyramid Pattern:

   • As the loops execute, asterisks are printed in a pyramid pattern. Each row has one more asterisk than the previous row, resulting in a triangular shape.
