c语言 结构体

#include <stdio.h>
#define SIZE 5
#define LEN 40
struct birth
{
int year;
int month;
};
struct student
{
int num;
char name[LEN];
int age;
char sex[LEN];
struct birth stu;
};

struct student getinfo(struct student *,int);
struct student showinfo(struct student);
int main(void)
{
int n=0;
int i;
struct student st[SIZE];
while(n<SIZE)
{
st[n]=getinfo(st,n);
n++;
}
return 0;

}


struct student getinfo(struct student *temp,int n)
{
int i;
printf("NO is %d\n",n+1);
temp[n].num=n+1;
printf("please input the name:\n");
scanf("%s",temp[n].name);
printf("please input the age:\n");
scanf("%d",&temp[n].age);
printf("please enter sex(0 is boy, 1 is girl)");
scanf("%d",&i);
temp[n].sex=(i==0)?"boy":"girl";
printf("please input the birth:\n");
scanf("%d%d",&temp[n].stu.year,&temp[n].stu.month);
}


程序运行错误：student.c: In function ‘getinfo’:
student.c:46: error: incompatible types when assigning to type ‘char[40]’ from type ‘char * const’
请教需要怎么修改

[解决办法]
说的很清晰啊，类型不对，无法赋值。
不过你发帖子，排下版好吧，看起来好累，最好是这样：

#include <stdio.h>
#define SIZE 5
#define LEN 40
struct birth
{
int year;
int month;
};
struct student
{
int num;
char name[LEN];
int age;
char sex[LEN];
struct birth stu;
};

struct student getinfo(struct student *,int);
struct student showinfo(struct student);
int main(void)
{
int n=0;
int i;
struct student st[SIZE]; 
 
while(n<SIZE)
{
st[n]=getinfo(st,n);
n++;
}
return 0;

}


struct student getinfo(struct student *temp,int n)
{
int i;
printf("NO is %d\n",n+1);
temp[n].num=n+1;
printf("please input the name:\n");
scanf("%s",temp[n].name);
printf("please input the age:\n");
scanf("%d",&temp[n].age);
printf("please enter sex(0 is boy, 1 is girl)");
scanf("%d",&i);
temp[n].sex=(i==0)?"boy":"girl";
printf("please input the birth:\n");
scanf("%d%d",&temp[n].stu.year,&temp[n].stu.month);
}

[解决办法]
temp[n].sex=(i==0)?"boy":"girl";

这条语句犯下了错误：
不能够直接将字串赋值:
char str[20];
str="llo";这样是错误的，
需要使用strcpy函数。

所以你的程序报错。这是关于c的内存方面使用注意的东西，尤其需要小心
[解决办法]
参考：

#include <stdio.h>
#include <string.h>
#define SIZE 5
#define LEN 40
struct birth
{
int year;
int month;
};
struct student
{
int num;
char name[LEN];
int age;
char sex[LEN];
struct birth stu;
};

struct student getinfo(struct student *,int);
struct student showinfo(struct student);
int main(void)
{
int n=0;
int i;
struct student st[SIZE];
while(n<SIZE)
{
st[n]=getinfo(st,n);
n++;
}

// 打印数组中的数据
for(int i = 0; i < SIZE; ++i)
{
printf("%d\t%s\t%d\t%s\t%d-%d\n", st[i].num, st[i].name, st[i].age, st[i].sex, st[i].stu.year, st[i].stu.month);
}

return 0;
}


struct student getinfo(struct student *temp,int n)
{
int i;
printf("NO is %d\n",n+1);
temp[n].num=n+1;
printf("please input the name:\n");
scanf("%s",temp[n].name);
printf("please input the age:\n");
scanf("%d",&temp[n].age);
printf("please enter sex(0 is boy, 1 is girl)");
scanf("%d",&i);
//temp[n].sex=(i==0)?"boy":"girl";   // 改为下面一句
strcpy(temp[n].sex, (i==0)?"boy":"girl");  
printf("please input the birth:\n");
scanf("%d%d",&temp[n].stu.year,&temp[n].stu.month);

return temp[n];  // 增加这一句 
 
}

[解决办法]
都是基础的知识。。。字符串赋值都是strcpy。。
