1 .編寫一個程式,該程式将随機生成的10個數(20-80)放入數組中,找出其中最大數及其下标。
<span style="font-family:SimSun;font-size:18px;">代碼如下:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace 随?機¨²數ºy數ºy組Á¨¦
{
class Program
{
static void Main(string[] args)
{
int i ;
int []a = new int[10];
int max = a[0];
int max_i = 0;
Random run =new Random();
for (i = 0; i < a.Length; i++)
{
a[i] = run.Next(20, 80);
}
for (i = 0; i < a.Length; i++)
{
Console.WriteLine("\t"+a[i]);
}
for (i = 0; i < a.Length; i++)
{
if (max < a[i])
{
max = a[i];
max_i = i;
}
}
Console.WriteLine("最大值:\t"+max);
Console.WriteLine("最大值下标\t"+ max_i);
Console.ReadLine();
}
}
}</span>
運作結果:

2.改寫上述程式,或自程式設計式,實作将其中最大的數與第一個數對換,最小的數與最後一個數對換。
代碼如下:
<span style="font-family:SimSun;font-size:18px;">using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace 随?機ú數簓數簓組哩?
{
class Program
{
static void Main(string[] args)
{
int max_i = 0;
int min_i = 0;
int i, temp, tempi;
int[] a = new int[10];
int max = a[0];
int min = a[9];
Random run = new Random();
for (i = 0; i < a.Length; i++)
{
a[i] = run.Next(20, 80);
}
Console.WriteLine("未′經-交?換?的?數簓組哩?:阰");
for (i = 0; i < a.Length; i++)
{
Console.Write(" " + a[i]);
}
Console.WriteLine();
for (i = 0; i < a.Length; i++)
{
if (max < a[i])
{
max = a[i];
max_i = i;
}
temp = a[0];
a[0] = a[max_i];
a[max_i] = temp;
}
Console.WriteLine("經-過y交?換?的?數簓組哩?:阰");
for (i = 0; i < a.Length; i++)
{
Console.Write(" " + a[i]);
}
Console.WriteLine();
Console.WriteLine("最?大洙?值μ:阰\t" + a[0]);
Console.ReadLine();
}
}
}</span>
