How do I make it so if the person has 2 or less absences, it adds 2 points to their average? Help!

#include <iostream>
#include <ctime>
#include <fstream>
#include <string>
#include <vector>
using namespace std;

struct Grade
{
	std::string last,
		first,
		middle,
		absence;
	double test1,
		   test2,
		   test3;


	friend std::istream &operator>>(std::istream &in, Grade &s)
	{
		return in >> s.last >> s.first >> s.middle >> s.test1 >> s.test2 >> s.test3 >> s.absence;
	}
	friend std::ostream &operator<<(std::ostream &out, const Grade &s)
	{
		return out << "Name: "      << s.first << " "    << s.middle << " " << s.last      << std::endl
			<< "Test Average: "  << (s.test1+s.test2+s.test3)/3  << std::endl
			<< "Absences: "  << s.absence  << std::endl;
	}
};


void main ()
{
	std::vector<Grade> grades;

	{
		std::ifstream infile ("students.txt");
		Grade temp;
		while(infile >> temp)
		{
			grades.push_back(temp);
		}
	}

	for(size_t i = 0; i < grades.size(); ++i)
	{
		std::cout << grades[i] << std::endl;
	}
}

I assume this is copy pasta'd code? Why is absence a string? Maybe have a method that actually computes the average, instead of sticking everything in operator<<. Then it's just a simple test.
