一维数组
int [] array = new int [5]{1,2,3,4,5};
int [] array = new int[5];
array[0] = 1;
array[1] = 2;
array[2] = 3;
array[3] = 4;
array[4] = 5;
array[5] = 6; 超出索引范围
int a = array[2];string [] ss = new string[3];
ss[0] = "1";
ss[1] = "2";
ss[2] = "3";
string b = ss[2];
输入三个人名放入数组
string[] name = new string[3];
Console.Write("请输入第一个人名:");
name[0] = Console.ReadLine();
Console.Write("请输入第二个人名:");
name[1] = Console.ReadLine();
Console.Write("请输入第三个人名:");

{
Console.Write("请输入第{0}个人名:",i);
name[i - 1] = Console.ReadLine();
}
//根据班级人数创建一个数组,要求每个人的姓名都要放进去
Console.Write("请输入班级人数:");
int n = int.Parse(Console.ReadLine());
string[] name = new string[n];
for (int i = 0; i < n; i++)
{
Console.Write("请输入第{0}个人的姓名:", i + 1);

}
Console.WriteLine("所有人员姓名输入完毕,请按回车键查看所有人员姓名!");
Console.ReadLine();
Console.WriteLine();
for (int i = 0; i < n; i++)
{
Console.Write(name[i] + "\t");
}
Console.ReadLine();
从控制台输入班级人数
将每个人的年龄放入数组,
将所有人的年龄求总和
求平均年龄
求年龄最大
Console.Write("请输入班级人数:");
int n = int.Parse(Console.ReadLine());
int [] age = new int[n];
int sum = 0;
for (int i = 0; i < n; i++)
{
Console.Write("请输入第{0}个人的年龄:",i+1);

sum+=age[i];
}
Console.WriteLine(sum);
Console.WriteLine(sum/n);
int agemax = 0;
for (int i = 0; i < n; i++)
{
if (agemax < age[i])
{
agemax = age[i];
}
}
Console.WriteLine("最大年龄是:"+agemax);
//冒泡排序
for (int i = 0; i < n; i++)
{

{
if (age[i] < age[j+1])
{
int zhong = age[i];
age[i] = age[j+1];
age[j+1] = zhong;
}
}
}
for (int i = 0; i < n; i++)
{
Console.WriteLine(age[i]);
}
Console.ReadLine();
//输入班级人数
//输入每个人的分数
//求总分、平均分、两个最高分,两个最低分
Console.Write("请输入班级的人数");
int n = int.Parse(Console.ReadLine());
double[] b = new double[n];
double fen = 0;
for (int i = 0; i < n; i++)
{
Console.Write("请输入{0}的分数:", i + 1);

fen += b[i];
}
Console.Write(fen);
Console.Write(fen/n);
Console.ReadLine();
