C# I want to use either a switch or if statement to select a sorting algorithm-CodePudding

I am writing a program that will take user input and run it through whichever sort they choose. Where I am having a problem is if I try to use a switch I cannot figure out how to add arguments to a switch or if I use an if statement how do I implement that with the user's input? here is the code and thank you all for your help. ''' using System;

namespace ASortAboveTheRest { internal class Program

{
    static void Main(string[] args)
    {
        MainMenu();
    }

    static void MainMenu()
    {

        Console.Clear();
        Console.WriteLine("Choose a sort algorithm to perform on the Array");
        Console.WriteLine("");
        Console.WriteLine("Option 1: Heap Sort");
        Console.WriteLine("Option 2: Bubble Sort");
        Console.WriteLine("Option 3: Shell Sort");

        Console.WriteLine("Please type: 1, 2, or 3");
        string myOption;
        myOption = Console.ReadLine();
        int[] arr = new int[10];
        int i;
        Console.Write("Input 10 elements in the array :\n");
        for (i = 0; i < 10; i  )
        {
            Console.Write("element - {0} : ", i);
            arr[i] = Convert.ToInt32(Console.ReadLine());
        }
        
        

        Console.Write("\nElements in array are: ");
        for (i = 0; i < 10; i  )
        {
            Console.Write("{0}  ", arr[i]);
        }
        Console.Write("\n");

CodePudding user response：

Following code should do the trick:

using System;

namespace ASortAboveTheRest { 
    internal class Program
    {
        static void Main(string[] args)
        {
            MainMenu();
        }

        static void MainMenu()
        {

            Console.Clear();
            Console.WriteLine("Choose a sort algorithm to perform on the Array");
            Console.WriteLine("");
            Console.WriteLine("Option 1: Heap Sort");
            Console.WriteLine("Option 2: Bubble Sort");
            Console.WriteLine("Option 3: Shell Sort");

            Console.WriteLine("Please type: 1, 2, or 3");
            // Take Option input as an INT
            int myOption;
            myOption = Convert.ToInt32(Console.ReadLine());

            int[] arr = new int[10];
            int i;
            Console.Write("Input 10 elements in the array :\n");
            for (i = 0; i < 10; i  )
            {
                Console.Write("element - {0} : ", i);
                arr[i] = Convert.ToInt32(Console.ReadLine());
            }



            Console.Write("\nElements in array are: ");
            for (i = 0; i < 10; i  )
            {
                Console.Write("{0}  ", arr[i]);
            }
            Console.Write("\n");
            
            //Use switch case after taking array input from the user
            switch(myOption) {
            case 1:
                //Call Heap Sort Function and pass your array
                break;
            case 2:
                // Call Bubble Sort Function and pass your array
                break;
            case 3:
                //Call Shell Sort Function and pass your array
                break;
            default:
                break;
            }
        }
    }
}
