18.2 数组和切片

创建：  `arr1 := new([len]type)`

        `slice1 := make([]type, len)`

初始化：`arr1 := [...]type{i1, i2, i3, i4, i5}`

        `arrKeyValue := [len]type{i1: val1, i2: val2}`

        `var slice1 []type = arr1[start:end]`

（1）如何截断数组或者切片的最后一个元素：

`line = line[:len(line)-1]`

（2）如何使用for或者for-range遍历一个数组（或者切片）：

for i:=0; i < len(arr); i++ {
… = arr[i]
}
for ix, value := range arr {
…
}

（3）如何在一个二维数组或者切片arr2Dim中查找一个指定值V：

found := false
Found: for row := range arr2Dim {
    for column := range arr2Dim[row] {
        if arr2Dim[row][column] == V{
            found = true
            break Found
        }
    }
}
