c++ - 在VS19中调试C++时出现错误代码0x80070002

Question

我对C++编程非常陌生
我正在用C++学习OOP，我想自己编写一个程序

    class Account
    {
    private:
        string name;
        double balance;
    public:
        Account();
        Account(string name_val);
        Account(double bal_val);
        Account(string name_val, double bal_val);
    };

那是上课

Account::Account(): name { "None" }, balance{ 0.0 }{}
Account::Account(string name_val) : name{ name_val }, balance{ 0.0 }{}
Account::Account(double bal_val) : name{ "None" }, balance{ 0.0 }{}
Account::Account(string name_val, double bal_val) : name{ name_val }, balance{ bal_val }{}

这些是我所做的声明

Account empty;
    Account frank{ "Frank" };
    Account rich_boi{ 1000000.0 };
    Account sad_boi{ "Sad boi", -10.0  };

这些是我主要制作的对象

编辑:在此之前，我还做了一个程序(我是从udemy类(class)获得的)
这是类

class Player
{
private:
    string name;
    int health;
    int xp;
public:
    //Overloaded Constructors
    Player();
    Player(string name_val);
    Player(string name_val, int health_val, int xp_val);
};

这些是构造函数

Player::Player() : name{ "None" }, health{ 0 }, xp{ 0 }{}

Player::Player(string name_val) : name{ name_val }, health{ 0 }, xp{ 0 }{}

Player::Player(string name_val, int health_val, int xp_val) : name{ name_val }, health{ health_val }, xp{ xp_val }{}

这些是主要的对象

    Player empty;
    Player frank{ "Frank" };
    Player villain{ "Villain" , 100 , 55 };

我正在添加在我的计算机上成功执行的完整代码。复制并执行以查看代码是否在您的末端成功执行。

#include<iostream>
using namespace std;

class Account
    {
    private:
        string name;
        double balance;
    public:
        Account();
        Account(string name_val);
        Account(double bal_val);
        Account(string name_val, double bal_val);
    };


 Account::Account(): name ( "None" ), balance( 0.0 ){}

 Account::Account(string name_val) : name( name_val ), balance(0.0 ){}

 Account::Account(double bal_val) : name("None" ), balance(bal_val ){}

 Account::Account(string name_val, double bal_val) : name( name_val ), balance( bal_val ){}

 int main(){
     Account empty;
     Account frank("Frank" ); 
     Account rich_boi( 1000000.0 );  
     Account sad_boi( "Sad boi", -10.0 );
 }
