c# Write piecewise function to find the solution

This answer quotes ChatGPT

C# console application to implement the required segmentation function:

using System;

class Program
{
    static void Main(string[] args)
    {
        Console.Write("请输入 x 的值：");
        double x = double.Parse(Console.ReadLine());

        if (x < 5)
        {
            double y = 2 * x + 5;
            Console.WriteLine("y = {0}", y);
        }
        else if (x == 5)
        {
            double y = 0;
            Console.WriteLine("y = {0}", y);
        }
        else
        {
            double y = x * x + 10;
            Console.WriteLine("y = {0}", y);
        }

        Console.ReadKey();
    }
}

1. First print a prompt through the Console.Write function for the user to enter the value of x.
2.Read the x value entered by the user through the Console.ReadLine function and store it in the x variable.
3. Use the if-else structure to implement the piecewise function. If x < 5, then execute the first piecewise function, calculate y = 2 * x + 5; If x = 5, then the second piecewise function is executed, calculating y = 0; If x > 5, then execute the 44th and the third piecewise functions to calculate y = x * x + 10.
5. Output the calculation result and print the result using the Console.WriteLine function.
6. Finally, use the Console.ReadKey function to wait for the user to press any key to end the program.
