我有一个简单的程序，可以计算四种不同工人类型的工资。它是按语义编写的，但我想重构它，这样我就可以让每个工作类型都成为它自己的类。
程序的主要控制在switch语句中。我想做的是为每种工作类型创建一个类，然后使用适当的 setter 和 getter 执行正确的计算。
工资单.cpp
#include <iostream>
#include <iomanip>
using namespace std;
// Function Prototype
void userPrompt (void);
int main ()
{
// declare paycode and salary
int paycode;
double salary;
// run user prompt function, input paycode
userPrompt ();
cin >> paycode;
while( paycode != -1 ) {
//switch statement to handle user input
switch( paycode ) {
case 1: // manager
cout << "Manager Selected." << endl;
cout << "Enter Weekly Salary: ";
// calculate manager's salary
cin >> salary;
cout << "Manager's pay is $" << std::fixed << setprecision( 2 ) << salary << "\n" << endl;
break;
case 2: // hourly worker
double wage;
int hours;
cout << "Hourly worker Selected." << endl;
cout << "Enter the hourly salary: ";
cin >> wage;
cout << "Enter the total hours worked: ";
cin >> hours;
// calculate hourly worker's pay
// with respect to possible overtime
if ( hours <= 40 )
salary = hours * wage;
else
salary = 40.0 * wage + ( hours - 40 ) * wage * 1.5;
cout << "Hourly worker's pay is $" << std::fixed << setprecision( 2 ) << salary << "\n" << endl;
break;
case 3: // commission worker
int sales;
cout << "Commission Worker Selected." << endl;
cout << "Enter gross weekly sales: ";
cin >> sales;
// calculate commission worker's pay
salary = sales * 0.092 + 250;
cout << "Commission worker's pay is $" << std::fixed << setprecision( 2 ) << salary << "\n" << endl;
break;
case 4: // widget worker
int widgets, wagePerWidget;
cout << "Widget Worker Selected." << endl;
cout << "Enter number of pieces: ";
cin >> widgets;
cout << "Enter wage per piece: ";
cin >> wagePerWidget;
// calculate widget worker's pay
salary = widgets * wagePerWidget;
cout << "Widget Worker's pay is $" << std::fixed << setprecision( 2 ) << salary << "\n" << endl;
break;
}
// prompt user to input paycode again or exit
cout<< "Enter paycode (-1 to end): ";
cin >> paycode;
}
exit (0);
}
// userPrompt function declaration
void userPrompt (void)
{
// prompt user to input paycode
cout << "Enter paycode (-1 to end): ";
}
