用C++写代码：创建一个 Employee 类，该类中有字符数组，表示姓名、街道地址、市、省和邮政编码。把表示构造函数、ChangeName()、Display()的函数原型放在类定义中,构造函数初始化每个成员,Display()函数把完整的对象数据打印出来。其中的数据成员是保护的,函数是公共的。将姓名构成类 Name,其名和姓在该类中为保护数据成员,其构造函数为接收一个指向完整姓名字符串的指针,其 Display()函数输出姓名。然后将Employee 类中的姓名成员(字符数组)换成 Name 类对象。将所有原型化的函数加上成员函数定义,作为类的内部实现文件构成完整的类库定义,要求类定义与类的成员函数定义分开。

以下是完整的类库定义：

Employee.h

#ifndef EMPLOYEE_H
#define EMPLOYEE_H

#include "Name.h"

class Employee {
protected:
    Name name;
    char address[100];
    char city[50];
    char state[50];
    char zip[20];
public:
    Employee(const char* fullName, const char* address, const char* city, const char* state, const char* zip);
    void ChangeName(const char* fullName);
    void Display() const;
};

#endif

Employee.cpp

#include "Employee.h"
#include <iostream>

Employee::Employee(const char* fullName, const char* address, const char* city, const char* state, const char* zip)
    : name(fullName) {
    strcpy_s(this->address, address);
    strcpy_s(this->city, city);
    strcpy_s(this->state, state);
    strcpy_s(this->zip, zip);
}

void Employee::ChangeName(const char* fullName) {
    name = Name(fullName);
}

void Employee::Display() const {
    std::cout << "Name: ";
    name.Display();
    std::cout << "Address: " << address << std::endl;
    std::cout << "City: " << city << std::endl;
    std::cout << "State: " << state << std::endl;
    std::cout << "Zip: " << zip << std::endl;
}

Name.h

#ifndef NAME_H
#define NAME_H

class Name {
protected:
    char firstName[50];
    char lastName[50];
public:
    Name(const char* fullName);
    void Display() const;
};

#endif

Name.cpp

#include "Name.h"
#include <iostream>

Name::Name(const char* fullName) {
    // Split full name into first and last names
    int spaceIndex = strchr(fullName, ' ') - fullName;
    strncpy_s(firstName, fullName, spaceIndex);
    firstName[spaceIndex] = '\0';
    strcpy_s(lastName, fullName + spaceIndex + 1);
}

void Name::Display() const {
    std::cout << firstName << " " << lastName << std::endl;
}
