		}
	}
	system("pause");
	return 0;
}

整体思路

  1. 显示菜单
  2. 创建通讯录的结构体(嵌套联系人的结构体数组+联系人个数)
  3. 根据菜单建立选择分支
  4. 完善各个分支的内容

功能主体部分

int main()
{
	//创建通讯录结构体变量
	Addressbooks abs;
	//初始化通讯录中当前人员个数
	abs.m_Size = 0;

     int select = 0;//选择
	while (true)
	{
		//菜单调用
		menu();
		cout << "选择功能(0-6)" << endl;
		cin >> select;
		switch (select)
		{
		//1.添加联系人
		case 1:
			addPerson(&abs);//利用地址传递可以修饰实参
			break;
		//2.显示联系人
		case 2:
			showPerson(&abs);
			break;
		//3.删除联系人
		case 3:
			deletePerson(&abs);
			break;
		//4.查找联系人
		case 4:
			findPerson(&abs);
			break;
		//5.修改联系人
		case 5:
			modifPerson(&abs);
			break;
		//6.清空联系人
		case 6:
			cleanPerson(&abs);
			break;
		//0.退出通讯录
		case 0:
			cout << "欢迎下次使用" << endl;
			system("pause");//按下任意键退出代码
			return 0;
			break;
		default:
			cout << "输入不在选项内,请重新输入" << endl;
			break;
		}
	}
	system("pause");
	return 0;
}

菜单 

void menu()
{
	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;
}

创建联系人结构体和通讯录的结构体

struct Person
{
	string m_Name;//姓名
	int m_Sex;//1.男 2.女
	int m_Age;//年龄
	string m_Phone;//电话
	string m_Addr;//地址

};
//通讯录的结构体
struct Addressbooks
{
	//通讯录中保存的联系人数组
	struct Person personArray[MAX];

	//通讯录中当前记录联系人个数
	int m_Size;
};

    	}
    	else

    		//添加具体联系人
    		//姓名
    		string name;
    		cout << "请输入姓名: " << endl;
    		cin >> name;
    		abs->personArray[abs->m_Size].m_Name = name;
    		//性别
    		cout << "请输入性别: " << endl;
    		cout << "1--男" << endl;
    		cout << "2--女" << endl;
    		int sex = 0;

    	cout << "通讯录已清空" << endl;
    	system("pause");
    	system("cls");
    }

    如果写在同一个文件中,会十分拥挤,我们可以新建一个函数定义的文件在源文件(后缀.cpp)中,函数声明的文件在头文件(后缀.h)中。
