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;
};
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;
};

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);
   printf("name = ",);
   scanf("%s", parr.name);
   printf("score = ");
   scanf("%f",&parr.score);
}

//排序
for (i=0; i<len; ++i)
{
for (j=0; j<len-1-i; ++j)
{
if (parr.score > parr.score)
{
      t = parr;
      parr = parr;
   parr = 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.age);

   printf("name = %s\n", parr.name);

   printf("score =%f\n",parr.score);

   printf("\n");
}
         return 0;
}
