结构体赋值

Question

假设现在有结构体struct student  student1, student2//结构体变量名

我能不能先申明，然后再初始化呢，上面是申明，下面再student1 = {}；student2 = {}

在编译的时候出现error：expected expression before ‘{’token

不知道为什么，有人能够解释一下其中的原理吗？

代码如下：

#include<stdio.h>

typedef struct weapon{

int price;

int rtk;

char name[20];

struct weapon *next;

}W;

int main()

{

W *head;

W w1,w2,w3;

 w1 ={100,200,"ijnjin",NULL};

 w2 ={1400,24400,"ifafadfjnjin",NULL};

 w3 ={13400,204440,"ifdfsdfsdjnjin",NULL};

head = &w1;

W *p = head;

while(p!=NULL){

printf("the price is %d,the nane is %s,the rtk is %d\n",p->price,p->name,p->rtk);

p = p->next;

}

return 0;

}

W w1 ={100,200,"ijnjin",NULL}; W w2 ={1400,24400,"ifafadfjnjin",NULL}; W w3 ={13400,204440,"ifdfsdfsdjnjin",NULL};输出：the price is 100,the nane is ijnjin,the rtk is 200单独定义就行了

Answer 3

#include<stdio.h>typedef struct weapon{int price;int rtk;char name[20];struct weapon *next;}W;int main(){ W *head;W w1,w2,w3; w1 ={100,200,"ijnjin",NULL}; w2 ={1400,24400,"ifafadfjnjin",NULL}; w3 ={13400,204440,"ifdfsdfsdjnjin",NULL}; head = &w1; W *p = head; while(p!=NULL){ printf("the price is %d,the nane is %s,the rtk is %d\n",p->price,p->name,p->rtk); p = p->next; } return 0;}

Answer 4

当然可以，那个报错是声明结构体变量名的问题吧，最好你把你报错的代码发出来看看
