Thread: classes and objects

I have done this :

Code:

#include<iostream>
#include<string>

class student
{
	private: 
	
	int score;
	string surname;
	
	public:
	
	student(string asurname, int ascore);
	~student();
	string getSurname();
	int getScore();
};
	student::student(string asurname, int ascore)
	{
		surname = asurname;
		score = ascore;
	}
	
	student::~student()
	{
	}
	
	string student::getSurname()
	{
		return surname;
	}
	
	int student::getScore()
	{
		return score;
	}


using namespace std;


int main()
{
	student Mike("Senikoglou", 20);
	cout << Mike.getSurname();
	cout << Mike.getScore();
	
	return 0;
}

having the class and the main fuction on the same cpp file, but how can I use 2 different files one for the class and one for the tester file(the main)???
