# 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]`
`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）：
