🔄 C# While Loop

The while loop in C# repeatedly executes a block of code as long as a specified condition is true. It's useful when you don’t know beforehand how many times the loop will run.

📘 Syntax

while (condition)
{
    // code to execute
}
  

💡 How It Works

• The condition is evaluated before each iteration.
• If condition is true, the loop body runs.
• The process repeats until the condition becomes false.

📄 C# Example: While Loop

using System;

class Program
{
    static void Main()
    {
        int count = 1;
        while (count <= 5)
        {
            Console.WriteLine($"Count is: {count}");
            count++;
        }
    }
}
    

📝 Sample Output

Count is: 1
Count is: 2
Count is: 3
Count is: 4
Count is: 5

📌 Summary

• The while loop checks the condition first before running.
• If the condition starts false, the loop body won’t execute even once.
• Use while loops for situations where the number of iterations is not fixed.
