基本上,我试图找出对象构造函数,析构函数和类。我创建了一个类,其中包含一些公共成员变量和一些私有成员变量。此时,我只在代码中使用了public成员。
我的问题是,简单地说,我如何利用构造函数、析构函数,并将对象的信息打印到控制台。
谢谢。
#include <iostream>
// Class -> NPC
// Contains generic stats for an NPC in a game
class NPC
{
public:
char name;
int age;
char favoriteItem;
private:
char quest;
char nemesis;
int karma;
}
// Object Constructor
NPC::NPC (char newName, int newAge, char newFavoriteItem)
{
name = newName;
age = newAge;
favoriteItem = newFavoriteItem;
}
// Object Deconstructor
NPC::~NPC()
{
// Do nothing
}
// Here I would like to create a new NPC, bob, with a name of "Bob", age of 28, and his favorite items being a Sword
// Next, I attempt to use this information as output.
int main()
{
NPC bob("Bob",28, "Sword");
std::cout << bob << std::endl;
}
将字符(只有一个字符)固定为std::string。我增加了初始化列表和std::ostream &operator <<
操作符。
#include <iostream>
#include <memory>
#include <string.h>
class NPC
{
public:
std::string name;
int age;
std::string favoriteItem;
NPC(std::string const& name, int age, std::string favoriteItem)
: name(name), age(age), favoriteItem(favoriteItem)
{};
private:
char quest;
char nemesis;
int karma;
};
std::ostream &operator << (std::ostream &os, NPC const& npc)
{
os << npc.name << " " << npc.age << " " << npc.favoriteItem << "n";
return os;
};
int main()
{
NPC npc("Bob", 28, "Sword");
std::cout << npc;
return 0;
}
