帮忙看看那里出错了？？？

# include <stdio.h>
# include <string.h>

struct student
{
   int age;
   char sex;
   char name;
};

void input(struct student *);
void output(struct student *);

int main(void)
{   
    struct student st;
    input(&st);
    output(&st);
   
    return 0;
}

void input(struct student *pst)
{
  (*pst).age = 10;

 错误在这--> strcpy(pst->name, "王二");
  pst->sex = '男';

   return ;
}

void output(struct student *pstu)
{  
    printf ("%d%c%c",pstu->age,pstu->name,pstu->sex);

   return ;
}
