C#取三个数的最大值、最小值、平均值、中间值

1、

class Program
{
static void Main(string[] args)
{
double a = Convert.ToDouble(Console.ReadLine());
double b = Convert.ToDouble(Console.ReadLine());
double c = Convert.ToDouble(Console.ReadLine());

//最大值
double max = a > b ? a : b;
max = max > c ? max : c;
Console.WriteLine("三个数最大值：{0}", max);

//最小值
double min = a < b ? a : b;
min = min < c ? min : c;
Console.WriteLine("三个数最小值：{0}", min);

//取三个数的中间值
double medians = median(a, b, c);
Console.WriteLine("三个数中间值：{0}", medians);

//取三个数的平均值
double avg;
avg = (a + b + c) / 3;
Console.WriteLine("三个数平均值：{0}", avg);

Console.WriteLine();
//中间值的15%
double z = (median(a, b, c)) * 0.15;

if ((max - medians) > z || (min - medians) > z)
{

Console.WriteLine("该组件的抗压强度值:{0}", median(a, b, c));
}

if ((max - medians) > z && (min - medians) > z)
{
Console.WriteLine("试验结果无效");
}

//三个数相同
if ((max - medians) < z || (min - medians) < z)
{

}
}
