18.2 数组和切片
最后更新于:2022-04-01 20:58:54
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
}
}
}
~~~
