Having trouble with llinker and Undefined reference errors
Im having difficulty compiling this program. I wrote a .h file that includes the class, constructor, mutator, and accessor functions-- a .cpp implementation file that includes the definitions of the functions, and the main .cpp program that tries to utilitze these functions. I've been trying to debug and have not found a solution. I broke down the problem into a simple task just to see if it will work but i still receive the linker error. The final program will have a derived class and its implementation file but i want to try to work in out in sections. In this example, im just trying to get it to work so im just using a single character for the employee name and just integers for the date ,not trying to get the whole string.Here's what i have as of yet:
employee.h
Code:
#ifndef EMPLOYEE_H
#define EMPLOYEE_H
class Employee
{
private:
char EmployeeName;// To hold the employee name
int EmployeeID;// To hold the employee ID
int HireDate;// To hold the employee hire date
public:
// constructor 1
Employee();
// constructor 2
Employee(char,int,int);
//Mutator function
void setName(char);
void setID(int);
void setDate(int);
//Accessor function
const char GetName() const
{return EmployeeName;}
int GetID() const
{return EmployeeID;}
int GetDate() const
{return HireDate;}
};
#endif
employee.cpp(implementation file that has the function definitions)
Code:
#include "Employee.h"
#include<iostream>
#include<cstring>
using namespace std;
// The constructor function definition
Employee::Employee()
{
EmployeeName = '\0';
EmployeeID = 0;
HireDate = 0;
}
Employee::Employee(char n, int i,int d)
{
strcpy(EmployeeName, n);
EmployeeID = i;
HireDate = d;
}
//Mutator Definitions
void Employee::setName(char n)
{
strcpy(EmployeeName,n);
}
//------------
void Employee::setID(int i)
{
EmployeeID = i;
}
//-----------
void Employee::setDate(int d)
{
HireDate = d;
}
mainprogram.cpp (The main program file)
Code:
#include<iostream>
#include<cstring>
#include "Employee.h"
using namespace std;
int main()
{
int i,d;
char n;
cout<< "enter a letter";
cin >> n;
cout << "enter your ID";
cin >> i;
cout <<"enter your date";
cin >> d;
Employee pay(n,i,d);
cout << pay.GetID();
system("pause");
return 0;
}
I've only started learning the basics of c++ since last fall. Its becoming more challenging as i progress and would very much appreciate any assistance from the community. Thank you
