数组:定义一组同类型的指定个数的变量索引从0开始
int[] name=new int[n];
------------------------------------------------------
自动遍历数组:
foreach (int a in shu)
{
console.writeline(a);
}
上式相当于:
for( int i=0;i<shu.length;i++)
{
int a;
a=shu[i];
console.writeline(a);
}
----------------------------------------
等量代换:
int a=3,b=5;
int c;
c=a;
a=b;
b=c;
输入8个数并从大到小排序(冒泡排序)
int[] a = new int[8];
for (int i = 0; i < 8; i++)
{
a[i] = Convert.ToInt32(Console.ReadLine());
}
for (int i= 0; i < 8; i ++)
{ for (int j=i ;j <8; j ++)
{
if (a[i ] < a[j ])
{
int zhong;
zhong = a[i ];
a[i ] = a[j ];
a[j ] = zhong;
}
}
Console.WriteLine(a[i]);
}
Console.ReadLine();
