我學習C++從專業C++從Wrox的連接錯誤 - 未定義參考「命名空間::類::函數（）」
下面是一個簡單的僱員記錄程序
1的3個文件。 Employee.h
// Employee.h
#include <iostream>
namespace Records {
const int kDefaultStartingSalary = 30000;
class Employee
{
public:
Employee();
void promote(int inRaiseAmount = 1000);
void demote(int inDemeritAmount = 1000);
void hire(); // Hires or rehires the employee
void fire(); // Dismisses the employee
void display(); // Outputs employee info to the console
// Accessors and setters
void setFirstName(std::string inFirstName);
std::string getFirstName();
void setLastName(std::string inLastName);
std::string getLastName();
void setEmployeeNumber(int inEmployeeNumber);
int getEmployeeNumber();
void setSalary(int inNewSalary);
int getSalary();
bool getIsHired();
private:
std::string mFirstName;
std::string mLastName;
int mEmployeeNumber;
int mSalary;
bool fHired;
};
}
2.Employee.cpp
// Employee.cpp
#include <iostream>
#include "Employee.h"
using namespace std;
namespace Records {
Employee::Employee()
{
mFirstName = "";
mLastName = "";
mEmployeeNumber = -1;
mSalary = kDefaultStartingSalary;
fHired = false;
}
void Employee::promote(int inRaiseAmount)
{
setSalary(getSalary() + inRaiseAmount);
}
void Employee::demote(int inDemeritAmount)
{
setSalary(getSalary() - inDemeritAmount);
}
void Employee::hire()
{
fHired = true;
}
void Employee::fire()
{
fHired = false;
}
void Employee::display()
{
cout << "Employee: " << getLastName() << ", " << getFirstName() << endl;
cout << "-------------------------" << endl;
cout << (fHired ? "Current Employee" : "Former Employee") << endl;
cout << "Employee Number: " << getEmployeeNumber() << endl;
cout << "Salary: $" << getSalary() << endl;
cout << endl;
}
// Accessors and setters
void Employee::setFirstName(string inFirstName)
{
mFirstName = inFirstName;
}
string Employee::getFirstName()
{
return mFirstName;
}
void Employee::setLastName(string inLastName)
{
mLastName = inLastName;
}
string Employee::getLastName()
{
return mLastName;
}
void Employee::setEmployeeNumber(int inEmployeeNumber)
{
mEmployeeNumber = inEmployeeNumber;
}
int Employee::getEmployeeNumber()
{
return mEmployeeNumber;
}
void Employee::setSalary(int inSalary)
{
mSalary = inSalary;
}
int Employee::getSalary()
{
return mSalary;
}
bool Employee::getIsHired()
{
return fHired;
}
}
3.EmployeeTest.cpp
// EmployeeTest.cpp
#include <iostream>
#include <conio.h>
#include "Employee.h"
using namespace Records;
int main (int argc, char** argv)
{
std::cout <<"Testing the Employee class." << std::endl;
Employee emp;
emp.setFirstName("Marni");
emp.setLastName("Kleper");
emp.setEmployeeNumber(71);
emp.setSalary(50000);
emp.promote();
emp.promote(50);
emp.hire();
emp.display();
getch();
return 0;
}
當我complie EmployeeTest.cpp我得到一個鏈接
「[鏈接錯誤]未定義參考`記錄::員工::員工（）」
我知道它有一個簡單的回答，但我無法在幾個小時內解決這個問題。 任何幫助高度讚賞。
