C# Code - C# Array Problem

C# Code - C# Array Problem

By Admin - September 25, 2024

Here’s a C# code snippet with some issues. Identify and fix the problems:

using System;

public class Program
{
    public static void Main()
    {
        int[] numbers = {1, 2, 3, 4, 5};
        int sum = 0;

        for (int i = 0; i <= numbers.Length; i++)
        {
            sum += numbers[i];
        }

        Console.WriteLine("Sum: " + sum);
    }
}

Questions:

What is wrong with the code, and why might it cause an issue?
How would you fix it?

The main issue is that the loop condition should be i < numbers.Length instead of i <= numbers.Length.

Here’s the corrected code snippet:

using System;

public class Program
{
    public static void Main()
    {
        int[] numbers = {1, 2, 3, 4, 5};
        int sum = 0;

        for (int i = 0; i < numbers.Length; i++) // Changed from i <= numbers.Length
        {
            sum += numbers[i];
        }

        Console.WriteLine("Sum: " + sum);
    }
}

Explanation:

Issue: The loop condition i <= numbers.Length leads to an IndexOutOfRangeException because the valid indices for the array numbers are 0 through numbers.Length - 1.
Fix: Changing the loop condition to i < numbers.Length ensures that the loop iterates through valid indices only.
