private:static const int LIMIT = 25;string lname;//姓char fname[LIMIT];//名
public:Person() { lname = ""; fname[0] = '\0'; }Person(const string& ln, const char* fn = "Heyyou");void Show()const;void FormalShow()const;

#include "Person.h"Person::Person(const string& ln, const char* fn )
{strcpy_s(this->fname, fn);this->lname = ln;
}
void Person::Show() const
{cout << "名:" << this->fname << endl;cout << "姓:" << this->lname << endl;
