【C语言实现简单通讯录系统】本文实例为大家分享了C语言通讯录系统（增删改查），供大家参考，具体内容如下

全部代码如下所示：

#include #include using namespace std; const int MAX = 1000; //联系人结构体typedef struct person{string m_name; //姓名int m_sex; //性别 1 男，0 女int m_age; //年龄string m_phone; //电话string m_addr; //住址}person_t; //通讯录结构体typedef struct addressbooks{person_t personArray[MAX]; //通讯录中保存的联系人数组int m_size; //通讯录中人员个数}addressbooks_t; void showMenu(){cout << "************************" << endl; cout << "***** 1.添加联系人 *****" << endl; cout << "***** 2.显示联系人 *****" << endl; cout << "***** 3.删除联系人 *****" << endl; cout << "***** 4.查找联系人 *****" << endl; cout << "***** 5.修改联系人 *****" << endl; cout << "***** 6.清空联系人 *****" << endl; cout << "***** 0.退出通讯录 *****" << endl; cout << "************************" << endl; }void addPerson(addressbooks_t *abs){//判断通讯录是否满了，如果满了就不再添加if(abs->m_size == MAX){cout<< "通讯录已满，无法添加！" << endl; return ; }else{//添加具体联系人cout << "请输入姓名： "; cin >> abs->personArray[abs->m_size].m_name; int sex; while(true){cout << "请输入性别（1男，0女）： "; cin >> sex; if(sex == 1 || sex == 0){abs->personArray[abs->m_size].m_sex = sex; break; }else{cout << "输入有误，请重新输入！" << endl; }}cout << "请输入年龄： "; cin >> abs->personArray[abs->m_size].m_age; cout << "请输入电话： "; cin >> abs->personArray[abs->m_size].m_phone; cout << "请输入地址： "; cin >> abs->personArray[abs->m_size].m_addr; //更新通讯录人数++ abs->m_size; cout << "添加成功！" << endl; system("pause"); }}void displayPerson(addressbooks_t *abs){if(abs->m_size == 0){cout << "记录为空!" << endl; }else{cout << "姓名\t" << "年龄\t" << "性别\t" << "电话\t\t" << "地址\t\t" << endl; for(int i = 0; i < abs->m_size; ++i){cout << abs->personArray[i].m_name << "\t"; cout << abs->personArray[i].m_age << "\t"; cout << (abs->personArray[i].m_sex == 1 ?
