二、Contact.c文件
包含函数的实现
#include "contact.h"; //游戏菜单函数的实现 void menu() { printf("***********************************\n"); printf("*******1.Add 2.Del********\n"); printf("*******3.Modefi 4.Search*****\n"); printf("*******5.show 6.Clear******\n"); printf("*******7.sort 0.exit*******\n"); printf("***********************************\n"); } //扩容函数的实现 int IncMemmery(struct PeoInfo* abs) { struct Contact* ptr = (struct Contact*)realloc(abs->data, (abs->capacity + 3) * sizeof(struct Contact)); if (ptr == NULL) { perror("GetMemmery():"); return -1; } else { abs->data = ptr; abs->capacity += 3; return 1; } } //初始化通讯录函数的实现 void loadInfo(struct PeoInfo* abs) { FILE* pf; pf = fopen("Contact.txt", "rb"); if (pf == NULL) { perror("InitContact():"); return; } struct Contact tmp = { 0 }; while (fread(&tmp, sizeof(struct Contact), 1, pf)) { if (abs->length == abs->capacity) { IncMemmery(abs); } *(abs->data + abs->length) = tmp; abs->length++; } fclose(pf); pf == NULL; } void InitContact(struct PeoInfo* abs) { assert(abs); abs->length = 0; abs->data = (struct Contact*)malloc(MAX_LEG * sizeof(struct Contact)); abs->capacity = MAX_LEG; loadInfo(abs); } //查询信息是否存在函数的实现 int IsExist(struct PeoInfo* abs, char* name) { for (int i = 0; i < abs->length; i++) { if (strcmp(abs->data[i].name, name) == 0) { return i; } } return -1; } //添加通讯录消息函数的实现 void AddConInfo(struct PeoInfo* abs) { assert(abs); if (abs->capacity == abs->length) { int ret = IncMemmery(abs); if (ret == 1) { printf("扩容成功!\n"); } else { printf("扩容失败,内存不足!\n"); return; } } printf("请输入添加的姓名:>"); scanf("%s", abs->data[abs->length].name); printf("请输入添加的姓别:>"); scanf("%s", abs->data[abs->length].sex); printf("请输入添加的联系方式:>"); scanf("%s", abs->data[abs->length].tele); printf("请输入添加的住址:>"); scanf("%s", abs->data[abs->length].addr); printf("请输入添加的年龄:>"); scanf("%d", &(abs->data[abs->length].age)); abs->length++; printf("已成功添加联系人!\n"); } //删除指定信息函数的实现 void DelConInfo(struct PeoInfo* abs) { assert(abs); char name[MAX_NAME]; printf("请输入要删除通讯录的姓名:>"); scanf("%s", name); int ret = IsExist(abs, name); if (ret == -1) { printf("不存在此联系人!\n"); } else { for (int i = ret; i < abs->length; i++) { abs->data[i] = abs->data[i + 1]; } abs->length--; } } //修改制定信息函数的实现 void ModefiInfo(struct PeoInfo* abs) { char name[MAX_NAME]; printf("请输入要修改通讯录信息的姓名:>"); scanf("%s", name); int ret = IsExist(abs, name); if (ret == -1) { printf("要修改指定联系人不存在!\n"); } else { printf("请输入要修改的姓名:>"); scanf("%s", abs->data[ret].name); printf("请输入要修改的性别:>"); scanf("%s", abs->data[ret].sex); printf("请输入要修改的联系方式:>"); scanf("%s", abs->data[ret].tele); printf("请输入要修改的住址:>"); scanf("%s", abs->data[ret].addr); printf("请输入要修改的年龄:>"); scanf("%d", &(abs->data[ret].age)); printf("修改成功!\n"); } } //查询指定信息函数的实现 void SearchInfo(struct PeoInfo* abs) { assert(abs); char name[MAX_NAME]; printf("请输入要查询通讯录的姓名:>"); scanf("%s", name); int ret = IsExist(abs, name); if (ret == -1) { printf("要查找的信息不存在!"); } else { printf("%-20s\t%-10s\t%-20s\t%-20s\t%-10s\n","姓名","性别","联系方式","住址","年龄"); printf("%-20s\t%-10s\t%-20s\t%-20s\t%-10d\n", abs->data[ret].name, abs->data[ret].sex, abs->data[ret].tele, abs->data[ret].addr, abs->data[ret].age); printf("查询成功!\n"); } } //展示通讯录信息函数的实现 void ShowInfo(struct PeoInfo* abs) { assert(abs); printf("%-20s\t%-10s\t%-20s\t%-20s\t%-10s\n", "姓名", "性别", "联系方式", "住址", "年龄"); for (int i = 0; i < abs->length; i++) { printf("%-20s\t%-10s\t%-20s\t%-20s\t%-10d\n", abs->data[i].name, abs->data[i].sex, abs->data[i].tele, abs->data[i].addr, abs->data[i].age); } } //清空通讯录列表函数的实现 void ClearInfo(struct PeoInfo* abs) { assert(abs); struct Contact* ptr = (struct Contact*)realloc(abs->data, MAX_LEG * (sizeof(struct Contact))); if (ptr == NULL) { perror("ClearInfo():"); } else { abs->length = 0; abs->data = ptr; memset(abs->data, 0, MAX_LEG * sizeof(struct Contact)); abs->capacity = MAX_LEG; printf("清空通讯录成功!\n"); } } //排序通讯录函数的实现 int CmpByAge(const void* e1, const void* e2) { return ((struct Contact*)e1)->age - ((struct Contact*)e2)->age; } int CmpByName(const void* e1, const void* e2) { return strcmp(((struct Contact*)e1)->name, ((struct Contact*)e2)->name); } void SortInfo(struct PeoInfo* abs) { getchar(); char ch; printf("请输入排序的方式:>N(姓名)、A(年龄),N or A:>"); ch = getchar(); if (ch == 'A') { qsort(abs->data, abs->length, sizeof(struct Contact), CmpByAge); printf("已按照年龄排序成功!\n"); } else if(ch == 'N') { qsort(abs->data, abs->length, sizeof(struct Contact), CmpByName); printf("已按照姓名排序成功!\n"); } else { printf("输入错误!\n"); } } //释放内存函数的实现 void FreeInfo(struct PeoInfo* abs) { free(abs->data); abs->data = NULL; } //保存通讯录函数的实现 void saveInfo(struct PeoInfo* abs) { FILE* pf; pf = fopen("Contact.txt", "wb"); if (pf == NULL) { perror("saveInfo():"); return; } for (int i = 0; i < abs->length; i++) { fwrite(abs->data + i, sizeof(struct Contact), 1, pf); } fclose(pf); pf = NULL; }
三、test.c文件
包含主函数即代码思想
#include "contact.h"; int main() { int input = 0; struct PeoInfo con; //初始化结构体 InitContact(&con); do { menu(); printf("请选择:>"); scanf("%d", &input); switch (input) { case 1: AddConInfo(&con); break; case 2: DelConInfo(&con); break; case 3: ModefiInfo(&con); break; case 4: SearchInfo(&con); break; case 5: ShowInfo(&con); break; case 6: ClearInfo(&con); break; case 7: SortInfo(&con); break; case 0: saveInfo(&con); FreeInfo(&con); printf("退出通讯录!"); break; default: printf("选择错误!\n"); } } while (input); return 0; }
