各位帮帮忙

yiweizero

不知道是我的软件问题,还是我的学的不到家.些个简单的程序没事.但是写个稍微复杂一点的总是报错,.我今天写了两个很多语言的程序.都报错,.
但是些简单就没有报错。我估计是我写错了，但是我又不知道，错在哪里?谁帮看看   真心求教,.感激不尽


这是第一个:
# include<stdio.h>
# include<string.h>

struct student
{     int age;
       char **;
       char name[100];
};
void inpustudent (struct student stu)
int main(void)
{   
    struct student st;
  
    inpustudent(st);   
   //OutputsStudent();
   
   printf("%d %c %s",st.age, st.**, st,name);
   return 0;
}

void inpustudent (struct student stu)
{
       stu.age = 10;
       stu.** = 'F';
       strcpy(stu.name,"张三");
}

这是第二个:
# include<stdio.h>
# include<malloc.h>

struct student
{
   int age;
   float score;
   char name[100];
};

main(void)

{
   int len;
   int * parr;
   int i;
   
   
   printf("请输入学生的个数:\n");
   printf("len = ");
   scanf("%d",&len);

   parr = (struct student *)malloc(len * sizerof(struct student));

   for (i=0; i<len; ++i)
   {
      printf("请输入第%d个学生的信息: ", i+1);
      printf("age = ");
      scanf("%d", &parr[i]);
      printf("name = ",);
      scanf("%s", parr[i].name);
      printf("score = ");
      scanf("%f",&parr[i].score);
     }

   //排序
  for (i=0; i<len; ++i)
  {
   for (j=0; j<len-1-i; ++j)
   {
     if (parr[i].score > parr[j+1].score)
     {
          t = parr[j];
          parr[j] = parr[j+1];
           parr[j+1] = t;
     }
   }
  }
   //输出
   for (i=0;i<len;++i)
   {
      printf("第%d学生的信息是:\n ", i+1);
     
      printf("age = %d\n", parr[i].age);
     
      printf("name = %s\n", parr[i].name);
     
      printf("score =  %f\n",parr[i].score);
     
      printf("\n");
   }
            return 0;
}
