Question

我有一个名为Employee的班级和名为BenefitPackage的班级。我希望BenefitPackage成为Employee的属性。该程序包含一个带有类和原型的头文件，一个包含原型定义的definitions.cpp文件和一个包含main函数的source.cpp。

我无法编译。

这是我所拥有的，提前感谢：

标题文件：

#include <string>
#include <iostream>
#include <iomanip>

using namespace std;

class iEmployee {
public:
    virtual double calculatePay() = 0;
};
class Employee:public iEmployee {
protected:

    string firstName;
    string lastName;
    char gender;
    int dependents;
    double annualSalary;
    BenefitPackage _benefitPackage;

public:

    static int numEmployees;

    static void getEmployees() 
    {
        // gets employees up to 1000
        bool done = false;
        int empCount = 0;
        Employee employees[1000];
        do {
            Employee::numEmployees++;
            employees[empCount].setInfo();
            employees[empCount].displayAll();

        } while (done!=true && empCount < 1000);
    }

    // Below are prototypes for Employee Methods

    Employee();

对于初学者，将您的福利包类的定义移到其他类定义之上，以便编译器知道在其他类定义中将其作为类型遇到时的好处包。

或者，将它们分成单独的头文件，因为这将使您的项目更有条理。

将对象实例化为类成员C ++
