有人能告诉我为什么变量百分比= 0？它应该是33.3333对吗？(2/6)

因为当我运行下面的函数时,结果是

总行数= 6
奇数行= 2
奇数行百分比= 0

bool count_odd_lines(string a, string b)
{
    ifstream in;
    ofstream out;
    in.open(a.c_str());
    out.open(b.c_str()); 
    string s;
    int count = 0;
    int odd =  0;  
    if (in && out)
    {
        while (getline(in, s))
        {
            count++;
            if (s.length() % 2 != 0) odd++;
        }
        out << "Total lines = " << count << endl;
        out << "Odd lines = " << odd << endl;
        double percent = odd/count;
        out << "Percent odd lines = " …

这是我应该做的:

• 编写一个基类Worker和2个派生类HourlyWorker和SalariedWorker.每个工人都有姓名和工资率.

• 编写一个虚拟函数compute_pay(int hours),计算每个工人的每周工资.每小时工人在前40个小时内获得全额工资,并且在任何时间内都可以获得工资.无论实际的小时数是多少,受薪工人都会按小时工资支付40小时.

以下是我的代码,编译时没有错误.但计算都错了.我希望有人可以告诉我我的代码有什么问题.

#include <iostream>
#include <string>

using namespace std;

//////////// Worker /////////////////////////////
class Worker
{
    public:
        Worker();
        Worker(string name, int salary);
        void print();
        int compute_pay(int hours);
        string get_name();
        int get_salary();
    private:
        string name;
        int salary;
        int payout;
};

Worker::Worker() {salary = 0;}
Worker::Worker(string name, int salary)
{
    this->name = name;
    this->salary = salary;
}
void Worker::print()
{
    cout << "Worker name: " << this->name;
    cout << "Salary: " << this->salary;
} …
