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
}
}
}
