C ++无法从方法中计算工资

C++ unable cout salary from method

入口点是 int main() 所以我尝试调用 pwr.GetSalary 来计算外部字符串“Salary”和双精度值,但是程序没有打印出任何内容。 所以它是基数 class.

class Employee
{
    public:
        std::string FirstName;
        std::string LastName;
        std::string Patronymic;
        double Salary;
        Employee() {};
        explicit Employee(std::string FirstName, std::string LastName,
            std::string Patronymic, double Salary)
            : FirstName(FirstName), LastName(LastName),
            Patronymic(Patronymic), Salary(Salary) {}
        bool operator==(Employee other) const
        {
            if (this->FirstName == other.FirstName && 
                this->LastName == other.LastName && 
                this->Patronymic == other.Patronymic) 
                return true;
            else 
                return false;
        }
};

一个女儿 class 继承了基数 class...这是计算工资并打印出来的绝妙方法...

class Papersworker : public Employee
{
    private:
        std::string FirstName;
        std::string LastName;
        std::string Patronymic;
        double Salary;
    public:
        Papersworker() {};
        using Employee::Employee;
        const std::string Job = "Papersworker";
        std::map<std::string, double> Coefficient = 
        {
            {"Director", 4.2},
            {"Papersworker", 1.2},
            {"Guardian", 1.5},
            {"Programmer", 2.5}
        };
        void ChangeCoefficient(std::string Job, double NewCoefficient)
        {
            Coefficient[Job] = NewCoefficient;
        }
        void ChangeNameSalary(std::string FirstName, std::string LastName, std::string Patronymic, double Salary)
        {
            this->FirstName = FirstName;
            this->LastName = LastName;
            this->Patronymic = Patronymic;
            this->Salary = Salary;
        }
        void PrintPapersworker()
        {
            std::cout << "First name\t" << "Lastname\t" << "Patronymic\t" << "Salary\n" << this->FirstName << "\t\t" << this->LastName << "\t" << this->Patronymic << "\t" << this->Salary << "\n" << std::flush;
            for (const auto& i : this->Coefficient)
            {
                std::cout << i.first << " = " << i.second << ";\t" << std::flush;
            }
            std::cout << "\n------------------------------------------------------------\n" << std::flush;
        }
        double GetSalary(double Salary, std::string Job)
        {
            return Salary * this->Coefficient[Job];
        }
};

精彩的 int main() 部分。

int main()
{
   Papersworker pwr;
   double sr = 0.0;
   std::cout << "\nEnter director's salary\t" << std::flush; std::cin >> sr;
   std::cout << "\nSalary\t" << pwr.GetSalary(sr, "Director");
   return 0;
}

如果您看到一些不好的需要优化的地方,请不要介意回复。 ._.我不明白 classes 建筑技巧是怎么回事。 https://pastebin.com/p7HXaX80 P. S. 我的作业强制使用私人名字,姓氏,父名,薪水...... P. S. S. 但是,我现在使用 Visual Studio 2022 Preview 和最新的 C++。 https://imgur.com/a/N8cDK3n

Papersworker 的所有私有成员都隐藏了 Employee

的 public 成员
class Papersworker : public Employee {
 private:
  std::string FirstName;
  std::string LastName;
  std::string Patronymic;
  double Salary;
// ...
};

试试这个:Compiler Explorer(未测试,因为我现在很着急,回来时会看看)

另外,be carefulstd::map::operator []

您的代码将无法编译,因为 sr 变量未定义。
在 main() 的语句 std::cin >> sr; 中使用它之前定义 double sr; 并且(至少)程序将编译并与用户交互。

int main() {
  Papersworker pwr;
  std::cout << "\nEnter director's salary\t" << std::flush;
  double sr; // <- your missed variable
  std::cin >> sr;
  std::cout << "\nSalary\t" << pwr.GetSalary(sr, "Director");
}

程序使用输入 10 打印:

Enter director's salary 10

Salary  42

program does not print out anything

如果您将 _getch() 更改为 getch(),您的程序(您提供的 pastebin link)编译成功并连续打印,可以看到 here。但出于某种原因,它永远持续下去。由于您提供的 link 有大约 500 行代码,所以我没有查看为什么条件没有被破坏(或者程序是否有任何未定义的行为)。也许您可以缩小问题范围并再次编辑您的问题。
