目标是制作一个程序,当输入一系列数字时,会显示最小值和最大值。-99 将用作哨兵。
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace ConsoleApplication12
{
class Program
{
static void Main(string[] args)
{
double number = 0, maxValue = 0, minValue = 0;
string goOn = "Y";
Console.WriteLine("Please enter a series of numbers, when you wish to stop entering numbers please enter -99.");
Console.WriteLine("The smallest and largest values will then be displayed.");
Console.WriteLine("Remember not to enter -99 unless you want the series to end.");
do
{
while (!double.TryParse(Console.ReadLine(), out number))
Console.WriteLine("Please enter whole numbers only");
while (number != -99)
{
process(ref number, ref minValue, ref maxValue);
while (!double.TryParse(Console.ReadLine(), out number))
Console.WriteLine("Please enter whole numbers only");
}
Console.WriteLine("The smallest value is {0} and the largest value is {1}.", minValue, maxValue);
Console.WriteLine("Do you want to enter another series of numbers?");
Console.WriteLine("If so enter y, if you want to end press any other key");
goOn = Console.ReadLine();
if (goOn.ToUpper() == "Y")
{
Console.WriteLine("Please enter your set of numbers.");
Console.WriteLine("Remember not to enter -99 unless you want the series to end.");
}
} while (goOn.ToUpper() == "Y");
}
static void process(ref double minValue, ref double maxValue, ref double number)
{
if (number > maxValue)
{
number = maxValue;
}
if (number < minValue)
{
number = minValue;
}
}
}
}
我还没有学习数组、气泡或类,但这里有一些问题:
可能是因为获取最小值和最大值的方法,如果我输入 3、22、7、15、1,我将得到 15 而不是 22,因为值 22 已被丢弃并替换为 7。
最小值未显示,而是显示为 0
当输入非数字时,显示错误信息后,再输入更多数字,则 minValue 显示与 maxValue 相同。
