在 C++ 中使用类 [关闭]

Question

我正在尝试使用类，但程序无法运行。如何修复？请记住，我是 C++ 的初学者。

#include <iostream>
#include <string>
#include <fstream>// enable writing to and reading from files
#include <cstdlib>
#include <time.h>

using namespace std;
//Globals

class Person
{
public:
    Person() {cout<<"\n\tBuilding a Person.";}
    ~Person() {cout<<"\n\tDestroying a Person.";}
    //Accessor Methods
    void setPersonName(string X) {PersonName=X; }
    void setOccupation(string X) {Occupation=X; }
    void setLocation(string X) {Location=X; }
    void setReferences(string X) {References=X; }
    string GetPersonName() {return PersonName;}
    string GetOccupation() {return Occupation;}
    string GetLocation() {return Location;}
    string GetReferences() {return References;}
private:

这些是错误：

Answer 1

关键字private 和public 是这样拼写的，而不是大写首字母。

此外，拥有一个有成员 int Person; 的 Person 类似乎是消除混乱的好方法。
