c语言结构体指针数组,c语言指针与数组详解
C语言结构体指针数组怎么声明
我说明写在案例的备注里，你参考吧。
#includestdio.h
typedef?struct?st
{
????????int?id;
}ST,*STP;?//先定义类型???ST是结构类型???STP是结构指针类型
int?main()
{
????STP?st[2];//这里st就是你要的结构指针数组
????ST?st1,st2;//这里我定义了2个结构变量，并赋值，让指针数组的元素分别指向这两个变量地址
????st1.id=1;st2.id=2;
????st[0]=st1;
????st[1]=st2;
????printf("%d,%d\n",st[0]-id,st[1]-id);//打印指针数组指向地址内容
????return?0;
}
C语言编程指向结构体数组的指针
下面的程序是我以前写的，你稍微改改就能符合你的要求了
#include?stdio.h
#include?malloc.h
typedef?struct?st
{
????char?name[20];
????int?chinese;
????int?math;
????int?english;
????float?average;
}student;
void?swap(student?*a,?student?*b)
{
????student?temp?=?*a;
????*a?=?*b;
????*b?=?temp;
}
void?sort(student?*array,?int?n)
{
????int?i,?j,?flag;
????for?(i?=?0;?i??n?-?1;?i++)
????{
????????flag?=?1;
????????for?(j?=?0;?j??n?-?i?-?1;?j++)
????????{
????????????if?(array[j].average??array[j?+?1].average)
????????????{
????????????????swap(array?+?j,?array?+?j?+?1);
????????????????flag?=?0;
????????????}
????????}
????????if?(flag)
????????????break;
????}
}
void?print(student?*array,?int?n)
{
????int?i;
????printf("姓名\t语文\t数学\t英语\t平均成绩\n");
????for?(i?=?0;?i??n;?i++)
????{
????????printf("%s\t%d\t%d\t%d\t%f\n",?array[i].name,?array[i].chinese,
????????????array[i].math,?array[i].english,?array[i].average);
????}
}
int?main()
{
????int?number?=?9;
????int?i;
????student?*stu?=?(student?*)malloc(sizeof(student)?*?9);
????for?(i?=?0;?i??number;?i++)
????{
????????printf("请输入第%d个学生的姓名及成绩（姓名?语文?数学?英语成绩以空格隔开）：\n",?i?+?1);
????????scanf("%s?%d?%d?%d",?(*(stu?+?i)).name,?(*(stu?+?i)).chinese,?
????????????(*(stu?+?i)).math,?(*(stu?+?i)).english);
????????(*(stu?+?i)).average?=?((*(stu?+?i)).chinese?+?
????????????(*(stu?+?i)).math?+?(*(stu?+?i)).english)?/?(float)3.0;
????}
????print(stu,?number);
????sort(stu,?number);
????print(stu,?number);
????free(stu);
????return?0;
}
C语言编程问题：结构体数组及指针
struct student *list;
int count = ReadStudentInfo("假设这是文件名", list);
这个函数是这样被调用。
里面应该这样写
int ReadStudentInfo(const char* filename, struct student** pStudents)
{
*pStudents = (struct student*)malloc(sizeof(** pStudents) * n);//假设有n个学生
}
C语言的指针结构体数组问题
#include?stdio.h
#include?string.h
struct?stu{
int?num;
char?name[20];
char?sex;
float?score;
}boy[5]={{101,"li?ping",'m',45},
{102,"zhang?ping",'m',62.5},
{103,"he?fang",'m',92.5},
{104,"cheng?ling",'f',87},
{106,"wang?ming",'m',58}};
struct?node
{
struct?stu?num;
struct?node?*next;
};
main()?
{?
int?i=0,bjg=0;
struct?node?s[5]={0};
for?(i=0;i5;i++)
{
s[i].num.num?=?boy[i].num;
strcpy(s[i].num.name,boy[i].name);
s[i].num.sex?=?boy[i].sex;
s[i].num.score?=boy[i].score;
s[i].next=s[i+1];
}
s[4].next=NULL;
printf("不及格：\n");
for?(i=0;i5;i++)
{
if?(s[i].num.score60)
{
bjg++;
printf("[%d]?[%s]?[%c]?[%.2f]\n",s[i].num.num,s[i].num.name,s[i].num.sex,s[i].num.score);
}
}
printf("不及格人数【%d】\n",bjg);
}
不及格：
[101]?[li?ping]?[m]?[45.00]
[106]?[wang?ming]?[m]?[58.00]
不及格人数【2】
Press?any?key?to?continue
不贴代码我就不调了?自己写了个
不说别的?光是malloc也不对啊??你不malloc?struct?node吗？
不malloc?struct?node?你的next指针存哪里？
至于链表赋值我就不看了
