go语言渐入佳境[12]-array-创新互联

//声明三种方式
var arr [3]int
var arr2  = [4]int{1,2,3,4}

fmt.Printf("类型arr3: %T,类型arr4: %T\n",arr3,arr4)

fmt.Println("arr3的长度为：",len(arr3))
fmt.Println("arr3的下标为2：",arr3[2])

//遍历数组
for i:=0;i fmt.Println(arr3[i])
}
//遍历数组2

for _,value:=range arr3{

 fmt.Println(value)
}

//冒泡排序
