end of file found before return 0

C++

Ok, this is a wadge caculation that uses a class to create the functions.

I got this far but it keeps saying end of file found before return.
I can not see the problem any help here would be appreciated.

#include <iostream>
#include <string>
using namespace std;
class employee {
private:
	const static int MAX_HOURS = 40 ;
	string firstName;
	string lastName;
	int hours[MAX_HOURS];
	int numhours;
	int wadges;
public:
	// First Name
	string getFirstName() { return firstName; }
	void setFirstName(string name) { firstName = name; }
	void retrieveFirstName() {
		string emp;
		cout << "First Name: ";
		cin >> emp;
		setFirstName(emp);
	}
	// Last Name
	string getLastName() { return lastName;	}
	void setLastName(string name) {	lastName = name; }
	void retrieveLastName() {
		string emp;
		cout << "Last Name: ";
		cin >> emp;
		setLastName(emp);
	}
	// Num hours
	int getnumhours() { return numhours; }
	void setnumhours(int hours) {
		if (hours >= 0 && hours <= MAX_HOURS) {
			numhours = hours;
		} else { 
			numhours = 0;
		}
	}
	void retrievenumhours() {
		cout << "How many hours did you work? ";
		int thours;
		cin >> thours;
		setnumhours(thours);
	}
		
	
  // Wadges
	int getwadges() {return wadges;}
	void setwadges (int twadges){
		wadges = twadges;
	setwadges(twadges);
	}
	void retrievewadges() {
		cout << "Wadges per hour ? ";
		int wadges;
		cin >> wadges;
		setwadges(wadges);
	}
	void retrieve() {
		retrieveFirstName();
		retrieveLastName();
		retrievenumhours();
		retrievewadges();
	}
	double calwadges() {
	double total = 0;
	for (int i = 0; i < getnumhours(); i ++) {
	total += hours[i];
	
	
	
	
	
};

int main() {
	employee name ;
	name.retrieve();


	system("pause");
	return 0;
}
