C#代码问题：如何根据剩余鸡蛋数动态调整单复数表述

我是编程新手，现有一段C#代码大体可用，但需要实现：当剩余鸡蛋数量为1时，输出文本为“You have {0} eggs which equals {1} dozen and {2} egg left over.”；当剩余鸡蛋数量多于1时，输出文本中的“egg”变为“eggs”。目前代码始终显示“eggs”，不知道该如何修改。

原代码 #

using System;
using System.Diagnostics.Eventing.Reader;

namespace Q2
{
    public class Q2
    {
        static void Main()
        {
            // Keep the following line intact 
            Console.WriteLine("===========================");

            // Insert your solution here.
            int totaleggs = 0;

            
            Console.Write("Enter the number of chickens: ");
            int Chickens = Convert.ToInt32(Console.ReadLine());

            for (int i = 0; i < Chickens; i++)
            {
                
                Console.Write("Eggs: ");
                int egg = Convert.ToInt32(Console.ReadLine());

                if (egg > 0)
                {
                    totaleggs += egg;
                    Console.WriteLine("You have {0} eggs which equals {1} dozen and {2} eggs left over.", totaleggs, (int)(totaleggs / 12), totaleggs % 12);
                    Console.ReadLine();
                }
                else if (totaleggs % 12 ==1)
                {
                    Console.WriteLine("You have {0} eggs which equals {1} dozen and {2} egg left over.", totaleggs, (int)(totaleggs / 12),  totaleggs % 12);
                    Console.ReadLine();
                }
                else
                {
                    Console.WriteLine("You have {0} eggs which equals {1} dozen and {2} eggs left over.", totaleggs, (int)(totaleggs / 12), totaleggs % 12);
                    Console.ReadLine();
                }
            }
            
            // Keep the following lines intact
            Console.WriteLine("===========================");
        }
    }
}

问题分析 #

原代码的判断逻辑存在错误：

• 第一个if (egg > 0)分支直接输出固定带eggs的文本，完全忽略剩余鸡蛋数量是否为1，这是导致始终显示eggs的核心原因。
• else if的判断条件放在egg > 0之后，只有当输入的egg不大于0时才会触发，逻辑顺序完全颠倒。

修改方案 #

先计算剩余鸡蛋数量，再根据剩余数量决定输出的单复数形式，以下是两种简洁的实现方式：

方式一：分支判断输出 #

using System;
using System.Diagnostics.Eventing.Reader;

namespace Q2
{
    public class Q2
    {
        static void Main()
        {
            // Keep the following line intact 
            Console.WriteLine("===========================");

            // Insert your solution here.
            int totaleggs = 0;

            
            Console.Write("Enter the number of chickens: ");
            int Chickens = Convert.ToInt32(Console.ReadLine());

            for (int i = 0; i < Chickens; i++)
            {
                
                Console.Write("Eggs: ");
                int egg = Convert.ToInt32(Console.ReadLine());

                // 先更新总鸡蛋数
                if (egg > 0)
                {
                    totaleggs += egg;
                }

                // 计算剩余鸡蛋数
                int leftover = totaleggs % 12;
                // 根据剩余数量选择输出文本
                if (leftover == 1)
                {
                    Console.WriteLine("You have {0} eggs which equals {1} dozen and {2} egg left over.", totaleggs, (int)(totaleggs / 12), leftover);
                }
                else
                {
                    Console.WriteLine("You have {0} eggs which equals {1} dozen and {2} eggs left over.", totaleggs, (int)(totaleggs / 12), leftover);
                }
                Console.ReadLine();
            }
            
            // Keep the following lines intact
            Console.WriteLine("===========================");
        }
    }
}

方式二：三元运算符简化代码 #

直接在输出语句中用三元运算符动态选择单复数，让代码更精简：

using System;
using System.Diagnostics.Eventing.Reader;

namespace Q2
{
    public class Q2
    {
        static void Main()
        {
            // Keep the following line intact 
            Console.WriteLine("===========================");

            // Insert your solution here.
            int totaleggs = 0;

            
            Console.Write("Enter the number of chickens: ");
            int Chickens = Convert.ToInt32(Console.ReadLine());

            for (int i = 0; i < Chickens; i++)
            {
                
                Console.Write("Eggs: ");
                int egg = Convert.ToInt32(Console.ReadLine());

                if (egg > 0)
                {
                    totaleggs += egg;
                }

                int leftover = totaleggs % 12;
                // 三元运算符判断单复数
                string eggWord = leftover == 1 ? "egg" : "eggs";
                Console.WriteLine($"You have {totaleggs} eggs which equals {(int)(totaleggs / 12)} dozen and {leftover} {eggWord} left over.");
                Console.ReadLine();
            }
            
            // Keep the following lines intact
            Console.WriteLine("===========================");
        }
    }
}

核心说明 #

• 先更新总鸡蛋数，再通过totaleggs % 12计算剩余鸡蛋数量。
• 根据剩余数量是否等于1，动态选择输出egg或eggs，确保逻辑正确。
