Custom Step Patterns
When you use a for loop in C#, you often see the loop variable increase by 1 each time through the loop. This is called the increment. However, you can customize this step value to fit your needs. By changing the increment or decrement, you can make your loop variable increase or decrease by any number, not just 1. This is useful for processing every nth item, skipping elements, or working with data in reverse order. Custom step values give you more control and flexibility for specialized data processing tasks.
Program.cs
123456789101112131415161718using System; namespace ConsoleApp { public class Program { public static void Main(string[] args) { string[] colors = { "Red", "Green", "Blue", "Yellow", "Purple", "Orange", "Pink" }; Console.WriteLine("Every third color in the array:"); for (int i = 0; i < colors.Length; i += 3) { Console.WriteLine(colors[i]); } } } }
Custom step values are especially helpful when you want to filter or sample data efficiently. For instance, you might want to process every other element in a list, or sample data points at regular intervals. By adjusting the increment or decrement in your for loop, you can easily skip over unwanted elements and focus only on those that meet your criteria.
Program.cs
1234567891011121314151617using System; namespace ConsoleApp { public class Program { public static void Main(string[] args) { Console.WriteLine("Counting down from 100 to 0 in steps of 10:"); for (int i = 100; i >= 0; i -= 10) { Console.WriteLine(i); } } } }
In real-world programming, custom step loops are useful in many situations. You might use them to sample sensor data at regular intervals, process only even or odd indexed items, or paginate through records in a database.
1. How does changing the increment value affect loop execution?
2. Which for loop prints every second element in an array?
