數組

一維數組數組

數組初始化，建立數組，數組長度爲5dom

int [] array=new int[5];排序

array[0] = 1;索引

array[1] = 2;數學

array[2] = 3;string

array[3] = 4;it

array[4] = 5;數據類型

直接賦值的數組數據

int[] array1 = new int[] {1,2,3,4,5 };二維數組

數組，在建立的時候，須要規定數據類型，初始長度

二維數組

int [,] shuzu = new int[3,4];

3 表示有3個一維數組

4 表示每個一維數組有4個元素

給第一個一維數組的2號索引賦值

shuzu[0, 2] = 3;

直接賦值

int[,] shuzu1 = new int[,] {

{1,2,3,4},

{2,3,4,5},

{3,4,5,6}

};

冒泡排序

for (int i = 0; i < 10;i++ )

{

for (int j =i; j < 9;j++ )

{

if(shuzi[i]<shuzi[j+1])

{

int zhong = shuzi[i];

shuzi[i] = shuzi[j + 1];

shuzi[j + 1] = zhong;

}

練習：

輸入人數，輸入每一個人年齡，求總和

// Console.Write("請輸入班級人數：");

// int n = int.Parse(Console.ReadLine());

// int [] ban=new int[n];

//int sum=0;

// for (int i = 0; i < n; i++)

// {

// Console.Write("請輸入年齡：");

// ban [i]=int.Parse(Console.ReadLine());

// sum += ban[i];

// }

// Console.WriteLine("年齡的總和是"+sum);

// Console.ReadLine();

輸入班級人數，存放語數英成績，求每人總和，語文總分，數學平均分

//Console.Write("請輸入班級人數：");

//int n = int.Parse(Console.ReadLine());

//double[,] chengji = new double[n, 3];

//double a = 0;

//double yz = 0;

//double sp = 0;

//for (int i = 0; i < n; i++)

//{

// Console.Write("請輸入語文成績：");

// chengji[i, 0] = double.Parse(Console.ReadLine());

// Console.Write("請輸入數學成績：");

// chengji[i, 1] = double.Parse(Console.ReadLine());

// Console.Write("請輸入英語成績：");

// chengji[i, 2] = double.Parse(Console.ReadLine());

//}

//for (int j = 0; j < n; j++)

//{

// a = chengji[j, 0] + chengji[j, 1] + chengji[j, 2];

// Console.WriteLine("第{0}我的的三門成績總和是{1}", (j + 1), a);

//}

//for (int k = 0; k < n; k++)

//{

// yz += chengji[k, 0];

//}

//Console.WriteLine("語文成績的總和是：" + yz);

//for (int p = 0; p < n; p++)

//{

// sp += chengji[p, 1];

//}

//Console.WriteLine("數學平均分紅績的是：" + (sp / n));

//Console.ReadLine();

打印柴，利用二維數組

//string[,] mingzi = new string[16, 10]

//{

//{" "," "," ","●"," "," ","","●","",""},

//{" "," "," ","●"," "," ","●"," "," ",""},

//{" ","●"," ","●"," "," ","●"," "," ","●"},

//{" ","●"," ","●"," "," ","●"," ","●",""},

//{" ","●"," ","●","●","●","●","●","",""},

//{" ","●"," ","●"," "," ","●","","",""},

//{" ","●"," ","●"," "," ","●","","","●"},

//{"●","●","●","●","●"," ","●","●","●",""},

//{" "," "," "," ","●","","","","",""},

//{" ","●","●","●","●","●","●","●","●",""},

//{" "," "," ","●","●","●","","","",""},

//{" "," ","●"," ","●"," ","●","","",""},

//{" ","●"," "," ","●"," "," ","●","",""},

//{"●"," "," "," ","●"," "," "," ","●",""},

//{" "," "," "," ","●"," "," "," "," ",""},

//};

//for(int i=0;i<16;i++)

//{

//for(int b=0;b<10;b++)

//{

//Console.Write(mingzi[i,b]);

//}

//Console.WriteLine();

//}

//Console.ReadLine();

隨機一百之內10個數，按照大小順序排列

int[] shuz = new int[10];

Random shu = new Random();

for (int i = 0; i < 10; i++)

{

int a = shu.Next(101);

shuz[i] = a;

Console.WriteLine(shuz[i]);

}

for (int j = 0; j < 10; j++)

{

for (int k = j; k < 9; k++)

{

if (shuz[j] > shuz[k + 1])

{

int zhong = shuz[j];

shuz[j] = shuz[k + 1];

shuz[k + 1] = zhong;

}

for (int i = 0; i < 10; i++)

{

Console.WriteLine(shuz[i]);

}

Console.ReadLine();

隨機一百之內十個不重複的數，按照大小順序排列。

// int[] shuz = new int[10];

//Random shu=new Random();

// for (int i = 0; i < 10; i++)

// {

// bool b=true;

// int a = shu.Next(101);

// shuz[i] = a;

// for (int j = 0; j < i; j++)

// {

// if (a == shuz[j])

// {

// b = false;

// i--;

// }

// if (b)

// {

// shuz[i] = a;

// }

// Console.WriteLine(shuz[i]);

// }

// for (int j = 0; j < 10; j++)

// {

// for (int k = j; k < 9; k++)

// {

// if (shuz[j] > shuz[k + 1])

// {

// int zhong = shuz[j];

// shuz[j] = shuz[k + 1];

// shuz[k + 1] = zhong;

// }

// for (int i = 0; i < 10; i++)

// {

// Console.WriteLine(shuz[i]);

// }

// Console.ReadLine();

//Random ran = new Random();

//輸入每一個人的手機號，，進行滾動顯示，，清屏，隨即一個索引，根據索引打印，等待0.1秒

// Console.Write("請輸入人數：");

// int a =int.Parse( Console.ReadLine());

// string[]zhj=new string[a];

// for (int i = 0; i < a;i++ )

// {

// Console.Write("請輸入第{0}我的的手機號：",(i+1));

// zhj[i] = Console.ReadLine();

// }

// Console.WriteLine("全部號碼輸入完畢，請按回車繼續抽獎活動！");

//Console.ReadLine();

// Random ran=new Random();

// for (int j = 0; j < 30;j++ )

// {

// Console.Clear();

// int aa = ran.Next(a);

// Console.WriteLine("中獎號碼是："+zhj[aa]);

// System.Threading.Thread.Sleep(100);

// }

// Console.ReadLine();
