openJudge | 统计学生信息(使用动态链表完成)C语言
总时间限制: 1000ms 内存限制: 65536kB
描述
利用动态链表记录从标准输入输入的学生信息(学号、姓名、性别、年龄、得分、地址)
其中,学号长度不超过20, 姓名长度不超过40, 性别长度为1, 地址长度不超过40
输入
包括若干行,每一行都是一个学生的信息,如:
00630018 zhouyan m 20 10.0 28#460
输入的最后以"end"结束
输出
将输入的内容倒序输出
每行一条记录,按照
学号 姓名 性别 年龄 得分 地址
的格式输出
样例输入
00630018 zhouyan m 20 10 28#4600
0063001 zhouyn f 21 100 28#460000
0063008 zhoyan f 20 1000 28#460000
0063018 zhouan m 21 10000 28#4600000
00613018 zhuyan m 20 100 28#4600
00160018 zouyan f 21 100 28#4600
01030018 houyan m 20 10 28#4600
0630018 zuyan m 21 100 28#4600
10630018 zouan m 20 10 28#46000
end
样例输出
10630018 zouan m 20 10 28#46000
0630018 zuyan m 21 100 28#4600
01030018 houyan m 20 10 28#4600
00160018 zouyan f 21 100 28#4600
00613018 zhuyan m 20 100 28#4600
0063018 zhouan m 21 10000 28#4600000
0063008 zhoyan f 20 1000 28#460000
0063001 zhouyn f 21 100 28#460000
00630018 zhouyan m 20 10 28#4600
答案
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
typedef struct node {
char data[9999999];
struct node *next;
} Node;
void addNode(Node **head, char data[]) {
Node *p = (Node*)malloc(sizeof(Node)), *q = *head;
strcpy((*p).data, data);
if(*head != 0) {
*head = p;
(*p).next = q;
} else {
*head = p;
(**head).next = NULL;
}
}
void readNode(Node **head) {
Node *last = *head;
while(last != 0) {
printf("%s\n", last->data);
last = last->next;
}
}
int main() {
Node *head = NULL;
static char data[9999999];
static int old, grade;
while(gets(data), strcmp(data, "end")) {
addNode(&head, data);
}
readNode(&head);
}
一些感想
其实,将学号 姓名 性别 年龄 得分 地址
看成是一个整体反而会好很多
这要感谢Looy_cai的6379:统计学生信息(使用动态链表完成)
至于,我之前写的是怎样的,看下面的代码
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
typedef struct node {
char id[20];
char name[40];
char sex;
int old;
int grade;
char address[40];
struct node *next;
} Node;
void addNode(Node **head, char id[], char name[], char sex, int old, int grade, char address[]) {
Node *p = (Node*)malloc(sizeof(Node)), *q = *head;
strcpy((*p).id, id);
strcpy((*p).name, name);
(*p).sex = sex;
strcpy((*p).address, address);
(*p).old = old;
(*p).grade = grade;
if(*head != 0) {
*head = p;
(*p).next = q;
} else {
*head = p;
(**head).next = NULL;
}
}
void readNode(Node **head) {
Node *last = *head;
while(last != 0) {
printf("%s %s %c %d %d %s\n", last->id, last->name, last->sex, last->old, last->grade, last->address);
last = last->next;
}
}
int main() {
Node *head = NULL;
static char id[20], name[40], sex, address[40], *p=id;
static int old, grade;
while(scanf("%s", id), strcmp(id, "end")) {
scanf("%s ", name);
scanf("%c", &sex);
scanf("%d", &old);
scanf("%d", &grade);
scanf("%s", address);
addNode(&head, id, name, sex, old, grade, address);
for(p = id; *p != 0; p++) {
*p = 0;
}
}
readNode(&head);
}
