C语言实现了通讯录的录入信息、保存信息、插入、删除、排序、查找、单个显示等功能。。

完整的代码如下：

#include #include //得到指向大小为Size的内存区域的首字节的指针//#include #include //标准库函数//#define NULL 0#define LEN sizeof(struct address_list) //计算字节// int n;struct address_list{char name[30]; //名字char work[30]; //职业char handset[30]; //手机char email[30]; //电子邮件char address[30]; //通讯地址struct address_list *next;};struct address_list *shifang(struct address_list *head); // 释放内存函数声明//创建函数，不带头结点的链表struct address_list *creat(void){struct address_list *head,*p1,*p2;char name[20];n=0;p1=(struct address_list *)malloc(LEN);p2=p1; //强制内存转换printf("请输入通讯录的内容!\n姓名输入为0时表示创建完毕!\n");printf("请输入姓名:");gets(name);if(strcmp(name,"0")!=0){strcpy(p1->name,name);printf("请输入职业:"); gets(p1->work);printf("请输入手机:"); gets(p1->handset);printf("请输入电子邮件:"); gets(p1->email);printf("请输入通讯地址:"); gets(p1->address);head=NULL;while(1){n=n+1; //记录通讯录人数个数if(n==1) head=p1;else p2->next=p1;p2=p1;printf("请输入姓名:");gets(name);if(strcmp(name,"0")==0){break;}else{p1=(struct address_list *)malloc(LEN);strcpy(p1->name,name);printf("请输入职业:"); gets(p1->work);printf("请输入手机:"); gets(p1->handset);printf("请输入电子邮件:"); gets(p1->email);printf("请输入通讯地址:"); gets(p1->address);}}p2->next=NULL;return head;}else return 0;}//输出函数void print(struct address_list *head){struct address_list *p;if(head!=NULL){p=head;printf("本通讯录现在共有%d人:\n",n);printf("---姓名-------职业--------手机-------Email-------通讯地址\n");printf("==================================\n");do{printf("== %s",p->name); printf(" ");printf("%s",p->work); printf(" ");printf("%s",p->handset); printf(" ");printf("%s",p->email); printf(" ");printf("%s",p->address); printf(" \n");p=p->next;}while(p!=NULL);printf("==================================\n");}else printf("通讯录为空,无法输出!\n");}//增加函数struct address_list *insert(struct address_list *head){struct address_list *p0,*p1,*p2;char name[20];p1=head;printf("请输入增加的内容:\n");printf("请输入姓名:"); gets(name);if(strcmp(name,"0")==0){printf("姓名不能为0,增加失败!\n");return(head);}else{p0=(struct address_list *)malloc(LEN);strcpy(p0->name,name);printf("请输入职业:"); gets(p0->work);printf("请输入手机:"); gets(p0->handset);printf("请输入电子邮件:"); gets(p0->email);printf("请输入通讯地址:"); gets(p0->address);n=n+1;if(head==NULL){head=p0;p0->next=NULL;return head;}else{while(strcmp(p0->name,p1->name)>0&&(p1->next!=NULL)){p2=p1;p1=p1->next;}if(strcmp(p0->name,p1->name)<0 || strcmp(p0->name,p1->name)==0){if(head==p1){head=p0;}else{p2->next=p0;}p0->next=p1;}else{p1->next=p0;p0->next=NULL;}return head;}}}struct address_list* delete_txl(struct address_list *head){struct address_list *p,*q;char name[30];if(head==NULL){printf("通讯录为空,无法显示!\n");return head;}p=head;printf("请输入需要删除的人的姓名:");gets(name);if(strcmp(head->name,name)==0){head=head->next;free(p);printf("删除操作成功！\n");return head;}else{q=head,p=head->next;while(p!=NULL){if(strcmp(p->name,name)==0){q->next=p->next;free(p);printf("删除操作成功！\n");return head;}p=p->next;q=q->next;}}}//显示函数struct address_list *display(struct address_list *head){struct address_list *p1,*p2;char name[30];int m;if(head==NULL){printf("通讯录为空,无法显示!\n");return head;}p1=head;m=0;printf("请输入需要显示人的姓名:");gets(name);while(p1!=NULL){while((strcmp(p1->name,name))!=0 && p1->next!=NULL){p2=p1;p1=p1->next;}if(strcmp(p1->name,name)==0){m++;printf("%s的通讯内容如下:\n",name);printf("---姓名--------职业--------手机-------Email------通讯地址\n");printf("==================================\n");printf("== %s",p1->name);printf(" ");printf("%s",p1->work);printf(" ");printf("%s",p1->handset);printf(" ");printf("%s",p1->email);printf(" ");printf("%s",p1->address); printf(" \n");printf("==================================\n");}p1=p1->next;}if(m==0){printf("此人未在本通讯录中!\n");}return(head);}
