C#入门5.11——跳转语句之return语句

return语句使用时一般有两种格式

1.return;

2.return表达式;

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace ConsoleApplication4
{
    class Program
    {
        static void Main(string[] args)
        {

            while (true)
            {
                Console.WriteLine("请输入三个数，按回车键确认每个数的输入：");
                double a = double.Parse(Console.ReadLine());
                double b = double.Parse(Console.ReadLine());
                double c = double.Parse(Console.ReadLine());
                double ave = average(a, b, c);
                Console.WriteLine("您输入三个数的平均值为{0}",ave);
            }
        }
        static double average(double a, double b, double c)
        {
            return (a + b + c) / 3;
        }
    }
}
