我正在制作一个C＃数学控制台项目，其中用户根据他们选择的难度回答加，减，乘，除，乘方或平方根问题！
但是，我的代码很好，我想不出第一个函数的好名字。
这是我的代码：
using System;
namespace mathstester
{
class Program
{
public enum UserDifficulty
{
Easy,
Normal,
Hard
}
public enum MathOperation
{
Addition = 1,
Subtraction = 2,
Multiplication = 3,
Division = 4,
Power = 5,
SquareRoot = 6
}
public static (int operationMin, int operationMax) GetOperation(UserDifficulty userDifficulty)
{
switch (userDifficulty)
{
case UserDifficulty.Easy:
return (1, 4);
case UserDifficulty.Normal:
return (1, 5);
case UserDifficulty.Hard:
return (3, 7);
default:
throw new Exception();
}
}
public static (string message, double correctAnswer) GetMathsEquation(MathOperation mathOperation, UserDifficulty userDifficulty)
{
int number1;
int number2;
Random randomNumber = new Random();
switch (mathOperation)
{
case MathOperation.Addition:
number1 = randomNumber.Next(1000);
number2 = randomNumber.Next(1000);
return ($"{number1} + {number2}", number1 + number2);
case MathOperation.Subtraction:
number1 = randomNumber.Next(1000);
number2 = randomNumber.Next(1000);
return ($"{number1} - {number2}", number1 - number2);
case MathOperation.Multiplication:
number1 = userDifficulty == UserDifficulty.Easy ? randomNumber.Next(13) : randomNumber.Next(1000);
number2 = userDifficulty == UserDifficulty.Easy ? randomNumber.Next(13) : randomNumber.Next(1000);
return ($"{number1} * {number2}", number1 * number2);
case MathOperation.Division:
number1 = randomNumber.Next(10000);
number2 = randomNumber.Next(1000);
return ($"{number1} / {number2}", number1 / (double)number2);
case MathOperation.Power:
number1 = randomNumber.Next(13);
number2 = randomNumber.Next(5);
return ($"{number1} ^ {number2}", Math.Pow(number1, number2));
case MathOperation.SquareRoot:
number1 = randomNumber.Next(1000);
return ($"√{number1}", Math.Sqrt(number1));
default:
throw new Exception();
}
}
public static int GetResult(int numberOfQuestionsLeft, UserDifficulty userDifficulty)
{
int score = 0;
Random random = new Random();
var (operationMin, operationMax) = GetMathOperationForDifferentDifficulties(userDifficulty);
while (numberOfQuestionsLeft > 0)
{
MathOperation mathOperation = MathOperation.Addition;
int mathRandomOperation = random.Next(operationMin, operationMax);
switch (mathRandomOperation)
{
case 1:
mathOperation = MathOperation.Addition;
break;
case 2:
mathOperation = MathOperation.Subtraction;
break;
case 3:
mathOperation = MathOperation.Multiplication;
break;
case 4:
mathOperation = MathOperation.Division;
break;
case 5:
mathOperation = MathOperation.Power;
break;
case 6:
mathOperation = MathOperation.SquareRoot;
break;
}
var (message, correctAnswer) = GetMathsEquation(mathOperation, userDifficulty);
if (mathRandomOperation == 4 || mathRandomOperation == 6)
{
Console.Write($"To the nearest integer, What is {message} =");
}
else
{
Console.Write($"What is {message} =");
}
double userAnswer = Convert.ToDouble(Console.ReadLine());
if (Math.Round(correctAnswer) == userAnswer)
{
Console.WriteLine("Well Done!");
score++;
}
else
{
Console.WriteLine("Your answer is incorrect!");
}
numberOfQuestionsLeft--;
}
return score;
}
public static void Main(string[] args)
{
string userInputDifficulty = "";
UserDifficulty userDifficulty = UserDifficulty.Easy;
do
{
Console.WriteLine("What difficulty level would you like to do! Please type E for Easy, N for Normal and H for hard");
userInputDifficulty = Console.ReadLine().ToUpper();
} while (userInputDifficulty != "E" && userInputDifficulty != "N" && userInputDifficulty != "H");
switch (userInputDifficulty)
{
case "E":
userDifficulty = UserDifficulty.Easy;
break;
case "N":
userDifficulty = UserDifficulty.Normal;
break;
case "H":
userDifficulty = UserDifficulty.Hard;
break;
}
int numberOfQuestions = 0;
do
{
Console.WriteLine("How many questions would you like to answer? Please type a number divisible by 10!");
int.TryParse(Console.ReadLine(), out numberOfQuestions);
} while (numberOfQuestions % 10 != 0);
int score = GetResult(numberOfQuestions, userDifficulty);
Console.WriteLine($"You got a score of {score} out of {numberOfQuestions}");
}
}
}
有人可以教我命名函数的最佳方法。
谢谢！
我应该命名为GetPossibleMathOperationForDifferentDifficulties
