class类中的函数声明后面跟const的意思是什么?
#pragma once#include<string>
using namespace std;
class Person
{
public:
Person(){ lname = ""; fname[0] = '\0'; }
Person(const string &ln, const char *fn = "Heyyou");
void Show()const;
void FormalShow()const;
private:
static const int LIMIT = 25;
string lname;
char fname[LIMIT];
};
