我的通讯录
我们准备用C语言实现一个通讯录
这个通讯录可容纳1000人的信息，涉及每个人的名字、年龄、性别、电话、地址
功能包括：
- 添加联系人
- 删除联系人
- 查找联系人
- 修改联系人信息
- 打印联系人信息
目录
一.菜单
二.测试函数、主函数
三.联系人信息及通讯录的实现
四.初始化通讯录
五.添加联系人函数
六.删除联系人函数
七.查找联系人函数
八.修改联系人函数
九.打印联系人函数
十.完整代码
一.菜单
void menu(){printf("\n");printf("\n");printf("* 1.add 2.del \n");printf("* 3.search 4.modify \n");printf("* 5.printf 0.exi \n");printf("\n");printf("\n");}二.测试函数、主函数
void test(){int input = 0;Contact con;InitialContact(&con);do{menu();printf("请选择:>\n");scanf("%d", &input);switch (input){case 1:AddContact(&con);break;case 2:DelContact(&con);break;case 3:SearchContact(&con);break;case 4:ModifyContact(&con);break;case 5:PrintContact(&con);break;case 0:printf("退出通讯录\n");break;default:printf("输入错误\n");break;}} while (input);}int main(){test();}三.联系人信息及通讯录的实现
typedef struct peoinfo{char name[NAME_MAX];int age;char sex[SEX_MAX];char tele[TELE_MAX];char addr[ADDR_MAX];}peoinfo;typedef struct Contact{peoinfo data[MAX];int sz;}Contact;四.初始化通讯录
void InitialContact(Contact *pc){assert(pc);pc->sz = 0;memset(pc->data, 0, sizeof(pc->data));}五.添加联系人函数
void AddContact(Contact *pc){assert(pc);if (pc->sz == MAX){printf("通讯录已经满啦！！！无法添加！！！\n");return ;}printf("请输入名字:\n");scanf("%s", pc->data[pc->sz].name);printf("请输入年龄:\n");scanf("%d", &(pc->data[pc->sz].age));printf("请输入性别:\n");scanf("%s", pc->data[pc->sz].sex);printf("请输入电话:\n");scanf("%s", pc->data[pc->sz].tele);printf("请输入地址:\n");scanf("%s", pc->data[pc->sz].addr);pc->sz++;printf("添加成功\n");}六.删除联系人函数
void DelContact(Contact *pc){assert(pc);if (pc->sz == 0){printf("您已经没有朋友了，无法删除\n");return;}char name[NAME_MAX];printf("请输入要删除人的名字:\n");scanf("%s", &name);int pos = FindByName(pc,name);if (pos == -1){printf("联系人不存在！\n");return;}int j = pos;for (j = pos; j sz-1; j++){pc->data[j] = pc->data[j + 1];}pc->sz--;printf("删除成功\n");}七.查找联系人函数
void SearchContact( Contact *pc){char name1[NAME_MAX];printf("请输入要查找人的名字:\n");scanf("%s", &name1);int pos = FindByName(pc, name1);if (pos == -1){printf("联系人不存在！\n");return;}printf("%-20s %-3s %-5s %-12s %-20s\n", "姓名", "年龄", "性别", "电话", "地址");printf("%-20s %-3d %-5s %-12s %-20s\n", pc->data[pos].name, pc->data[pos].age,pc->data[pos].sex, pc->data[pos].tele, pc->data[pos].addr);}int FindByName(const Contact *pc,char* name)/*找到返回下标，找不到返回-1*/{assert(pc);for (int i = 0; i sz; i++){if (strcmp(pc->data[i].name, name) == 0){return i;}}return -1;}八.修改联系人函数
void ModifyContact(Contact *pc){char name[NAME_MAX];printf("请输入要修改人的名字:\n");scanf("%s", &name);int pos = FindByName(pc, name);if (pos == -1){printf("联系人不存在！\n");return;}printf("请输入修改后的名字:\n");scanf("%s", pc->data[pos].name);printf("请输入修改后的年龄:\n");scanf("%d", &(pc->data[pos].age));printf("请输入修改后的性别:\n");scanf("%s", pc->data[pos].sex);printf("请输入修改后的电话:\n");scanf("%s", pc->data[pos].tele);printf("请输入修改后的地址:\n");scanf("%s", pc->data[pos].addr);printf("修改成功\n");}九.打印联系人函数
void PrintContact(const Contact *pc){assert(pc);printf("%-20s %-3s %-5s %-12s %-20s\n", "姓名","年龄", "性别", "电话", "地址");int i = 0;for (i = 0; i sz; i++){printf("%-20s %-3d %-5s %-12s %-20s\n", pc->data[i].name, pc->data[i].age,pc->data[i].sex, pc->data[i].tele, pc->data[i].addr);}}十.完整代码
