Module 6: Loops

Repeating a fixed number of times

for is the loop you reach for when you know how many times.

Program.cs

using System;

class Program
{
    static void Main()
    {
        for (int i = 1; i <= 3; i++)
        {
            Console.WriteLine($"Round {i}");
        }
    }
}

Output

Round 1
Round 2
Round 3

Three parts, separated by ;:

int i = 1 — where the counter starts
i <= 3 — keep going while this is true
i++ — what happens after each pass

i++

Shorthand for i = i + 1. There is also i += 2 to step by two.
