go中数组以及map的遍历方式

数组遍历:

1.for加上索引遍历

name := [2]string{"liqiang","lisan"}
for i :=0;i < len(name); i++ {
     fmt.PrintIn(name[i])
}

 

2.for range方式遍历

name := [2]string{"lisan","zhangsi"}
for index, value := range name {
     fmt.PrintIn(index.value)
}

 

map遍历

1.使用 for range 循环

relationship := map[string]sting{"lisan":"deskmate","lisi":"boss"}
for key,values := range relation{
   fmt.PrintIn(key,value)
}

2.使用 for range 循环遍历键或值：

myMap := map[string]int{"a": 1, "b": 2, "c": 3}
// 遍历键
for key := range myMap {
    fmt.Println(key)
}
// 遍历值
for _, value := range myMap {
    fmt.Println(value)
}
