从外部类中更改循环内的变量

Question

我有一个时间类和一个Build类。收获功能在整个时间内增加了矿物质数量，但是矿物质的数量取决于可用工人的数量。一旦构建开始，工作人员数量就会减少。 那么，如何在循环内减少工作者数量，而不是在循环结束后减少工作者数量。 我希望矿物质不断增加，但是根据Build调用，工人数量应该增加和减少。

class Time {
private:
    int minerals = 50;
        int workers = 6;
    int vespene = 0;
    int supply = 6;
    int time = 0;


public:
    Time ();
    int Time_counter();
    void harvest();
    int mineral_count();
    int worker_count();
    int supply_count();
    void update(int m, int w, int s, int t);
    void Display();
};

Time::Time ()
{
    for (int i =0; i<9; i++)
    {
        update(minerals, workers, supply, time);
        harvest();
        time = i;
       // Time_counter();
    }


}
int Time::Time_counter() {
        return time;

    minerals+= workers * (0.7);
