以下是完整代码实现：

#include<iostream>
#include<stdlib.h>
#include<string>
using namespace std;

class Employee {
public:
    virtual int earning() = 0;
};

class WeekWorker : public Employee {
public:
    WeekWorker(int salary = 580) : m_salary(salary) {}
    int earning() {
        return m_salary * 52;
    }
private:
    int m_salary;
};

class MonthWorker : public Employee {
public:
    MonthWorker(int salary = 2500) : m_salary(salary) {}
    int earning() {
        return m_salary * 12;
    }
private:
    int m_salary;
};

class YearWorker : public Employee {
public:
    YearWorker(int salary = 22000) : m_salary(salary) {}
    int earning() {
        return m_salary;
    }
private:
    int m_salary;
};

class Company {
public:
    Company() {}
    int salarypay() {
        int sum = 0;
        for (int i = 0; i < 30; i++) {
            sum += emp[i]->earning();
        }
        return sum;
    }
    Employee* emp[30];
};

int main() {
    Company co;
    for (int i = 0; i < 30; i++) {
        int r = rand() % 3 + 1;
        switch (r) {
        case 1:
            co.emp[i] = new WeekWorker(580);
            break;
        case 2:
            co.emp[i] = new MonthWorker(2500);
            break;
        case 3:
            co.emp[i] = new YearWorker(22000);
            break;
        default:
            break;
        }
    }
    cout << "company total pay=" << co.salarypay();
    return 0;
}

在上述代码中，我们定义了三个员工类 WeekWorker、MonthWorker 和 YearWorker，它们分别对应每周、每月和每年的薪水收入。在 Company 类中，我们使用了一个虚基类 Employee 来表示所有员工，然后通过继承实现了具体的员工类型。在 Company 类中，我们使用了一个 emp 数组来存放公司的员工，salarypay 函数则是计算公司的总薪水支出。最后，在主函数中，我们使用了一个 for 循环来随机生成公司的员工类型，并将其添加到公司中。最终，我们调用了 salarypay 函数来计算公司的总薪水支出，并将其打印出来。
