结构体嵌套调用有错误!

[stevenjin]

这种结构体嵌套调用有错吗?是林锐书里看到的.应该怎样才正确?

#include "stdafx.h"
#include <iostream>
#include <assert.h>
using namespace std;
#include <iostream>
using namespace std;

struct Student 
{
   int age;
   struct Name 
   {
      char firstName[30];
	  char secondName[30];
   };
  
};
void main()
{
    Student stu;
	char p[20]="name";
	stu.Name.firstName=p;
}

报错:
错误 2 error C2274: “函数样式转换”: 位于“.”运算符右边时非法 c:\documents and settings\administrator\my documents\visual studio 2005\projects\c++ project\c++ project\c++ project.cpp 22
错误 3 error C2228: “.firstName”的左边必须有类/结构/联合 c:\documents and settings\administrator\my documents\visual studio 2005\projects\c++ project\c++ project\c++ project.cpp 22

struct Student 
{
   int age;
   struct Name 
   {
      char firstName[30];
      char secondName[30];
   }name;
  
};
void main()
{
    Student stu;
    char p[20]="name";
    stu.name.firstName=p;
}

不是发过的吗
struct
{
char firstName[30];
char secondName[30];
} Name ;

#include "stdafx.h"

struct Student 
{
   int age;
   struct Name 
   {
      char firstName[30];
      char secondName[30];
   }name;//
  
};
void main()
{
    Student stu;
    char p[30]="name";
    stu.name.firstName=p;//
}

结构体的嵌套，外面结构体里面定义的必须是结构体变量，而你只是定义了结构体类型
