私は、4つの異なる労働者タイプの給与を計算するこの単純なプログラムを持っています。セマンティックに記述されていますが、各ワーカータイプを独自のクラスにできるように、リファクタリングしたいと思います。
プログラムの主な制御はswitchステートメントにあります。私がやりたいのは、ワーカータイプごとにクラスを作成し、適切なセッターとゲッターを使用して、適切な計算を実行することです。
payroll.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)
