c#制作计算器实现指数、对数、平方、开根号、正弦、余弦、绝对值代码

以下是C#制作计算器实现指数、对数、平方、开根号、正弦、余弦、绝对值的代码：

using System;

namespace Calculator
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("请输入第一个数字：");
            double num1 = Convert.ToDouble(Console.ReadLine());

            Console.WriteLine("请输入运算符：");
            string op = Console.ReadLine();

            double result = 0;

            switch (op)
            {
                case "^":
                    Console.WriteLine("请输入指数：");
                    double exponent = Convert.ToDouble(Console.ReadLine());
                    result = Math.Pow(num1, exponent);
                    break;
                case "log":
                    Console.WriteLine("请输入底数：");
                    double logBase = Convert.ToDouble(Console.ReadLine());
                    result = Math.Log(num1, logBase);
                    break;
                case "sqrt":
                    result = Math.Sqrt(num1);
                    break;
                case "sin":
                    result = Math.Sin(num1);
                    break;
                case "cos":
                    result = Math.Cos(num1);
                    break;
                case "abs":
                    result = Math.Abs(num1);
                    break;
                default:
                    Console.WriteLine("无效的运算符");
                    break;
            }

            Console.WriteLine("结果为：" + result);
        }
    }
}
