For Loop Tutorial | Syntax, Example & Output c#

🔁 For Loop in C#

The for loop in C# is used to repeat a block of code a specific number of times. It's one of the most common loops and is useful when you know in advance how many iterations you want.

📘 Syntax of for loop

for (initialization; condition; increment/decrement) {
    // Code to execute repeatedly
}
  

💡 How it works

• Initialization: executed once before the loop starts
• Condition: checked before each iteration; if true, loop continues
• Increment/Decrement: executed after each iteration

📝 Example: For Loop in C#

using System;

class Program {
    static void Main() {
        for (int i = 1; i <= 5; i++) {
            Console.WriteLine($"Iteration number: {i}");
        }
    }
}
  

📤 Sample Output

Iteration number: 1
Iteration number: 2
Iteration number: 3
Iteration number: 4
Iteration number: 5

🧠 Explanation

• The loop starts with i = 1.
• Before each iteration, it checks if i <= 5.
• On each iteration, it prints the current value of i.
• After printing, i increments by 1 (i++).
• The loop stops when i becomes 6, as the condition i <= 5 fails.

The for loop is a fundamental construct in C# programming and helps to run repetitive tasks efficiently and cleanly.
