1.以下代码有什么问题，说明原因
type student struct {
Name string
Age int
}
func pase_student() {
m := make(map[string]*student)
stus := []student{
{Name: "zhou", Age: 24},
{Name: "li", Age: 23},
{Name: "wang", Age: 22},
}
for _, stu := range stus {
m[stu.Name] = &stu
}
}
答：
阐述问题：会存在问题，最终m存储的值都会相同，即
m["zhou"] = &{Name: "zhou", Age: 24}
m["li"] = &{Name: "zhou", Age: 24}
m["wang"] = &{Name: "zhou", Age: 24}
分析问题：
for range代码被翻译成下面代码
for_temp := range
len_temp := len(for_temp)
for index_temp = 0; index_temp < len_temp; index_temp++ {
value_temp = for_temp[index_temp]
index = index_temp
value = value_temp
m[value.Name] = &value
}
则每一次循环中，存储起来的value指针其实都是同一个。
解决问题：
for _, stu := range stus {
temp := stu
m[stu.Name] = &temp
}
