本文通过一个简历类的实例介绍了深拷贝的概念及其实现方式。代码中定义了一个简历类并实现了克隆功能，展示了如何通过克隆创建一个包含相同属性但独立于原对象的新对象。

代码：

#include <iostream>
#include <string>

using namespace std;

class object
{
   public:
   object(){}
   virtual ~object(){}
   virtual object* clone() = 0;

};

class resume : public object
{
   private:
       string name;
       string sex;
       string age;
       string timeArea;
       string company;

   public:
       resume() {}
       virtual ~resume(){}

       resume(string m_name):name(m_name){}

       void setpersoninfo(string m_sex, string m_age)
       {
           sex = m_sex;
           age = m_age;
       }

       void setcompanyinfo(string m_timeArea, string m_company)
       {
           timeArea = m_timeArea;
           company = m_company;
       }

       void display()
       {
           cout<<"name: "<<name<<"\n";
           cout<<"sex: "<<sex<<"\n";
           cout<<"age: "<<age<<"\n";
           cout<<"timeArea: "<<timeArea<<"\n";
           cout<<"company: "<<company<<"\n";
       }

       resume* clone();

};
   resume* resume::clone()
   {
       return new resume(*this);
   }

int main()
{
   resume *a = new resume("lilei");
   a->setpersoninfo("男","28");
   a->setcompanyinfo("2014-2015","贝尔");
   a->display();

   resume *b = a->clone();
   b->setpersoninfo("男","27");
   b->setcompanyinfo("2014-2019","intel");
   b->display();

   return 0;
}

结果：

ngnsvr9 [** NONE **]/home/xionghailong/demo/res $ g++ main.cpp -o main
ngnsvr9 [** NONE **]/home/xionghailong/demo/res $ ./main
name: lilei
sex: 男
age: 28
timeArea: 2014-2015
company: 贝尔
name: lilei
sex: 男
age: 27
timeArea: 2014-2019
company: intel
