#include<stdio.h>//错误啊
#include<stdlib.h>

struct yi
{
    char name[10];
    int age;
    char address[20]; 
}

struct er
{
    struct yi *boy[3]; 
}

void main()
{int i;
    struct er *p;
    for(i=0;i<3;i++)
    scanf("%s%d%s",p->boy[i]->name,p->boy[i]->age,p->boy[i]->address);

        for(i=0;i<3;i++)
    printf("%s\t%d\t%s",p->boy[i]->name,p->boy[i]->age,p->boy[i]->address);    
}

分配空间后还是没用啊

#include<stdio.h>
#include<stdlib.h>

struct yi
{
    char name[10];
    int age;
    char address[20]; 
}
struct er
{
    struct yi boy[3]; 
}

void main()
{int i;
    struct er *p;
  p=(struct er*)malloc(sizeof(struct er));
    for(i=0;i<3;i++)
    scanf("%s%d%s",p->boy[i].name,p->boy[i].age,p->boy[i].address);

        for(i=0;i<3;i++)
    printf("%s\t%d\t%s",p->boy[i].name,p->boy[i].age,p->boy[i].address);

    
}

还是没用啊  

for(i=0;i<3;i++)
    p->boy[i]=(struct yi *)malloc(sizeof(struct yi));

要这样啊  谢谢

p=(struct er*)malloc(sizeof(struct er));
    for(i=0;i<3;i++)
    p->boy[i]=(struct yi *)malloc(sizeof(struct yi));

这样行啊

struct er
{
    struct yi boy[3];
}

这要怎么分配空间啊

#include<stdio.h>//错误啊
#include<stdlib.h>

struct yi
{
    char name[10];
    int age;
    char address[20];
};

struct er
{
    struct yi boy[3];
};

void main()
{int i;
    struct er *p;
    p=(struct er*)malloc(sizeof(struct er));

    for(i=0;i<3;i++)
    scanf("%s%d%s",p->boy[i]->name,&p->boy[i]->age,p->boy[i]->address);

        for(i=0;i<3;i++)
    printf("%s\t%d\t%s\n",p->boy[i]->name,p->boy[i]->age,p->boy[i]->address);   
}

这样不行  郁闷

struct yi
{
    char name[10];
    int age;
    char address[20];
};

struct er
{
    struct yi boy[3];
};

int main()
{
    int i;
    struct er *p;
    p=(struct er*)malloc(sizeof(struct er));

这样行，刚才搞错了

刚才忘记把'->'换成' . '了
