/*Test c++ program that test the employee object by creating an object of employee type and
display the employee object to console window.*/
//testemployeetime.cpp
#include<iostream>
#include "employeetime.h"
using namespace std;
int main()
{
   //create an object of employee class
   employee x("Smith", 124, 50000, 8,30);
   cout<<"x = ";
   //call write method
   x.write(cout);

   system("pause");
   return 0;
}

}

/*employee constructor

Sample Output:

x = {Smith, 124, 50000, 08:30}F
