Question

How to sort an array of strings where each string represents a decimal number in C#

Answer 1

using System;

public class SortDecimalStrings
{
    // Comparator method to sort strings as decimal numbers
    public static int CompareAsDecimal(string a, string b) {
        // Convert strings to double for comparison
        double numA = double.Parse(a);
        double numB = double.Parse(b);

        return numA.CompareTo(numB);
    }

    public static void Main(string[] args)
    {
        // Input array of strings
        string[] numbers = { "12.3", "5.6", "789.1", "3.14", "456.0", "0", "0.01", "4.0" };

        // Sort the array using the custom comparator
        Array.Sort(numbers, CompareAsDecimal);

        Console.WriteLine("Sorted array of decimal strings:");
        foreach (string num in numbers) {
            Console.Write(num + "  ");
        }
    }
}
