Thread: having trouble with overloading operator+

Hi,

i wanted to overload a + operator to add two objects..i have an error which states "invalid operands `employee *' and `employee *' to binary `operator +'".. i do not know what is wrong with that statement, can anyone pls point out my mistake?? Thanks.

Code:

//overloading example
//write an overloading function so u can add the salary of 2 employee objects

#include <iostream>
#include <string>
using namespace std;
const short kmaxlength= 50;



class employee
{
	protected:
	char name[kmaxlength];
	float salary;
	
	public:
	employee(char *emp_name, short sal);
	~employee();
	float getsalary();
};





//constructor
employee::employee(char *emp_name, short sal)
{
	strncpy(name, emp_name, kmaxlength);
	salary = sal;
	cout<<"creating employee: "<<name<<endl;
}





employee::~employee()
{
	cout<<"Deleting employee: "<<name<<endl;
}





float employee::getsalary()
{
	return salary;
}	





float operator+(employee obj1, employee obj2)
{
	return((obj1.getsalary() + obj2.getsalary()));
}





int main()
{
	employee *e1;
	e1 = new employee("Ryan", 1000);

	employee *e2;			
	e2 = new employee("Jack", 500);
	
                //Will this work instead of the above 4 lines??
	//employee e1("Ryan", 1000);
	//employee e2("Jack", 500);
	
	float total_salary = 0;
	
	total_salary = e1 + e2;
	
	return 0;
}
