程序代码

#include <iostream>
#include <Cstring>

using namespace std;

class CPerson //定义一个CPerson类
{
protected:
	char *m_szName;//姓名
	char *m_szId;//身份证号
	int m_nSex;//性别0:women,1:man
	int m_nAge;//年龄

public:
	CPerson(char *name,char *id,int sex,int age);//构造函数
	void Show1();//显示个人信息
	~CPerson();//需要释放建立对象时动态分配的内存
};

CPerson::CPerson(char *name,char *id,int sex,int age)//构造函数
{
    //动态内存分配
    m_szName = new char[strlen(name) + 1];
    m_szId = new char[strlen(id) + 1];

    //赋值
    strcpy(m_szName, name);
    strcpy(m_szId, id);

}

CPerson::~CPerson()//需要释放建立对象时动态分配的内存
{
    //释放内存
    delete []m_szName;
    delete []m_szId;
}

class CEmployee:public CPerson//CEmployee类继承CPerson类
{
private:
	char *m_szDepartment;//部门
	float m_Salary;//薪水

public:
    //构造函数
	CEmployee(char *name,char *id,int sex,int age,char *department,float salary);
	void Show2();//显示员工信息
	~CEmployee();
};

//构造函数
CEmployee::CEmployee(char *name,char *id,int sex,int age,char *department,float salary)  
:CPerson(name,id,sex,age)  
{  
    //动态内存分配
    m_szDepartment = new char[strlen(department) + 1];

    strcpy(m_szDepartment,department);//初始化部门  
    
    m_Salary = salary;//初始化工资
}

//显示员工信息
void CEmployee::Show2()
{
    char sex[10];

    if(0 == m_nSex)
    {
        strcpy(sex, "women");
    }
    else
    {
        strcpy(sex, "man");
    }

    cout<<"姓名\t"<<"身份证号码\t\t"<<"性别\t"<<"年龄\t"<<"部门\t"<<"工资"<<endl;
    cout<<m_szName<<"\t"<<m_szId<<"\t"<<sex<<"\t"<<m_nAge<<"\t"<<m_szDepartment<<"\t"<<m_Salary<<endl;
}

//析构函数
CEmployee::~CEmployee()
{
    //释放内存
    delete []m_szDepartment;
}


int main()
{
	char name[10],id[19],department[10];
	int sex,age;
	float salary;

	cout<<"请输入员工的姓名, 身份证号码, 性别(0:women,1:man), 年龄, 部门, 工资:"<<endl;
	cin>>name>>id>>sex>>age>>department>>salary;
	
    //初始化员工信息
    CEmployee employee1(name,id,sex,age,department,salary);
	
    //输出员工信息
    employee1.Show2();

    system("pause");
}

执行结果

当输入  张三的信息后输出的结果
