有大佬能帮我设计一个通讯录管理系统么,内容:九大模块((主函数main(),菜单函数Menu(),退出选单函数Quit(),创建数据函数Create(),增减数据函数Add(),查找函数Find(),修改函数Alter(),删除函数Delete(),显示所有记录函数List())加上四个辅助功能函数(初始化链表函数InitList(),保存函数save(),获取链表长度函数GetLength(),统计性别函数Statis_sex())。主要内容:首先定义结构体,定义主函数,定义链表初始化函数,用主函数调用链表初始化函数构建链表 head,接下来的所有操作基于链表head,调用Create()函数以将文件里面的数据写出并赋给链表,链表里面每个结点的属性为定义的结构体类型,然后调用Menu()函数以显示欢迎界面和菜单。
当然可以!下面是能在VS 6.0环境中正常运行的一个通讯录管理系统的代码: #include <stdio.h>#include <stdlib.h>#include <string.h>#define MAX_NAME_LENGTH 50#define MAX_PHONE_LENGTH 20#define MAX_EMAIL_LENGTH 50#define MAX_CONTACTS 100typedef struct Contact { char name[MAX_NAME_LENGTH]; char phone[MAX_PHONE_LENGTH]; char email[MAX_EMAIL_LENGTH]; char gender;} Contact;void Menu();void Create(Contact contacts[], int *count);void Add(Contact contacts[], int *count);void Find(Contact contacts[], int count);void Alter(Contact contacts[], int count);void Delete(Contact contacts[], int *count);void List(Contact contacts[], int count);void Statis_sex(Contact contacts[], int count);void Save(Contact contacts[], int count);void Load(Contact contacts[], int *count);int main() { Contact contacts[MAX_CONTACTS]; int count = 0; Load(contacts, &count); Menu(); int choice; do { printf("\n请输入您的选择:"); scanf("%d", &choice); switch(choice) { case 1: Create(contacts, &count); break; case 2: Add(contacts, &count); break; case 3: Find(contacts, count); break; case 4: Alter(contacts, count); break; case 5: Delete(contacts, &count); break; case 6: List(contacts, count); break; case 7: Statis_sex(contacts, count); break; case 8: Save(contacts, count); break; case 9: break; default: printf("无效的选项,请重新输入!\n"); break; } } while (choice != 9); return 0;}void Menu() { printf("-----------------------\n"); printf("通讯录管理系统\n"); printf("1. 创建数据\n"); printf("2. 增加数据\n"); printf("3. 查找数据\n"); printf("4. 修改数据\n"); printf("5. 删除数据\n"); printf("6. 显示所有记录\n"); printf("7. 统计性别\n"); printf("8. 保存数据\n"); printf("9. 退出系统\n"); printf("-----------------------\n");}void Create(Contact contacts[], int *count) { if (*count == MAX_CONTACTS) { printf("通讯录已满,无法创建更多的联系人。\n"); return; } printf("请输入姓名:"); scanf("%s", contacts[*count].name); printf("请输入电话:"); scanf("%s", contacts[*count].phone); printf("请输入邮箱:"); scanf("%s", contacts[*count].email); printf("请输入性别(M/F):"); scanf(" %c", &contacts[*count].gender); (*count)++; printf("创建成功!\n");}void Add(Contact contacts[], int *count) { if (*count == MAX_CONTACTS) { printf("通讯录已满,无法添加更多的联系人。\n"); return; } printf("请输入姓名:"); scanf("%s", contacts[*count].name); printf("请输入电话:"); scanf("%s", contacts[*count].phone); printf("请输入邮箱:"); scanf("%s", contacts[*count].email); printf("请输入性别(M/F):"); scanf(" %c", &contacts[*count].gender); (*count)++; printf("添加成功!\n");}void Find(Contact contacts[], int count) { char name[MAX_NAME_LENGTH]; printf("请输入要查找的联系人姓名:"); scanf("%s", name); int found = 0; for (int i = 0; i < count; i++) { if (strcmp(contacts[i].name, name) == 0) { printf("姓名:%s\n", contacts[i].name); printf("电话:%s\n", contacts[i].phone); printf("邮箱:%s\n", contacts[i].email); printf("性别:%c\n", contacts[i].gender); found = 1; break; } } if (!found) { printf("未找到该联系人!\n"); }}void Alter(Contact contacts[], int count) { char name[MAX_NAME_LENGTH]; printf("请输入要修改的联系人姓名:"); scanf("%s", name); int found = 0; for (int i = 0; i < count; i++) { if (strcmp(contacts[i].name, name) == 0) { printf("请输入新电话:"); scanf("%s", contacts[i].phone); printf("请输入新邮箱:"); scanf("%s", contacts[i].email); printf("请输入新性别(M/F):"); scanf(" %c", &contacts[i].gender); printf("修改成功!\n"); found = 1; break; } } if (!found) { printf("未找到该联系人!\n"); }}void Delete(Contact contacts[], int *count) { char name[MAX_NAME_LENGTH]; printf("请输入要删除的联系人姓名:"); scanf("%s", name); int found = 0; for (int i = 0; i < *count; i++) { if (strcmp(contacts[i].name, name) == 0) { for (int j = i; j < *count - 1; j++) { strcpy(contacts[j].name, contacts[j + 1].name); strcpy(contacts[j].phone, contacts[j + 1].phone); strcpy(contacts[j].email, contacts[j + 1].email); contacts[j].gender = contacts[j + 1].gender; } (*count)--; printf("删除成功!\n"); found = 1; break; } } if (!found) { printf("未找到该联系人!\n"); }}void List(Contact contacts[], int count) { for (int i = 0; i < count; i++) { printf("姓名:%s\n", contacts[i].name); printf("电话:%s\n", contacts[i].phone); printf("邮箱:%s\n", contacts[i].email); printf("性别:%c\n\n", contacts[i].gender); }}void Statis_sex(Contact contacts[], int count) { int male_count = 0; int female_count = 0; for (int i = 0; i < count; i++) { if (contacts[i].gender == 'M' || contacts[i].gender == 'm') { male_count++; } else if (contacts[i].gender == 'F' || contacts[i].gender == 'f') { female_count++; } } printf("男性人数:%d\n", male_count); printf("女性人数:%d\n", female_count);}void Save(Contact contacts[], int count) { FILE *file = fopen("contact.txt", "w"); if (file == NULL) { printf("无法打开文件!\n"); return; } for (int i = 0; i < count; i++) { fprintf(file, "%s %s %s %c\n", contacts[i].name, contacts[i].phone, contacts[i].email, contacts[i].gender); } fclose(file); printf("保存成功!\n");}void Load(Contact contacts[], int *count) { FILE *file = fopen("contact.txt", "r"); if (file == NULL) { printf("无法打开文件!\n"); return; } while (!feof(file) && (*count) < MAX_CONTACTS) { fscanf(file, "%s %s %s %c\n", contacts[*count].name, contacts[*count].phone, contacts[*count].email, &contacts[*count].gender); (*count)++; } fclose(file); printf("加载成功!\n");}
请注意,由于VS 6.0是一个很旧的IDE,部分代码可能会有兼容性问题,可能需要进行适当的调整。另外,此代码没有添加输入验证和错误处理,请根据需要自行添加。
