Challenge: Employee Pay

Lab C++ Intermediate 20 points

A base class Employee has a name and a virtual int pay() const. Salaried employees get a fixed monthly salary. Hourly employees get hours × rate, plus half their rate again for every hour over 160 (integer maths). Read n lines like salaried Ana 3000 or hourly Ben 170 20 and print Ana: 3000 etc.

Input

n, then n lines.

Output

One name: pay line per employee.

Example

Input

2
salaried Ana 3000
hourly Ben 170 20

Output

Ana: 3000
Ben: 3500

Hints

Hourly reads two numbers, Salaried reads one: check the kind before reading the rest.

Overtime extra: (hours - 160) * rate / 2, only when hours > 160.

Solution explanation

Each class knows how to work out its own pay; the main loop just calls pay() on every employee.

#include <iostream>
#include <string>
#include <vector>
using namespace std;

class Employee {
protected:
    string name;
public:
    Employee(string n) : name(n) {}
    string getName() const { return name; }
    virtual int pay() const = 0;
    virtual ~Employee() {}
};

class Salaried : public Employee {
    int salary;
public:
    Salaried(string n, int s) : Employee(n), salary(s) {}
    int pay() const override { return salary; }
};

class Hourly : public Employee {
    int hours, rate;
public:
    Hourly(string n, int h, int r) : Employee(n), hours(h), rate(r) {}
    int pay() const override {
        int total = hours * rate;
        if (hours > 160) {
            total += (hours - 160) * rate / 2;
        }
        return total;
    }
};

int main() {
    int n;
    cin >> n;
    vector<Employee*> staff;
    for (int i = 0; i < n; i++) {
        string kind, name;
        cin >> kind >> name;
        if (kind == "salaried") {
            int s;
            cin >> s;
            staff.push_back(new Salaried(name, s));
        } else {
            int h, r;
            cin >> h >> r;
            staff.push_back(new Hourly(name, h, r));
        }
    }
    for (Employee* e : staff) {
        cout << e->getName() << ": " << e->pay() << "\n";
        delete e;
    }
    return 0;
}
