//Question 12 answer
//Given this struct:
struct student
{
	string name;
	int credits;
	double grades[6];
};

student * highestGrade(student students[], int numberOfStudents)
{
	//Breaks if number of students is < 1, but the given input is going to be 41 students on the question.
	//Null means nothing.
	student * highest = NULL;
	double highestAverage = 0;
	for (int i = 0; i < numberOfStudents; i++)
	{
		//Get average.
		double average = 0;
		//Loop through all grades of students[i]
		for (int j = 0; j < 6; j++)
		{
			average += students[i].grades[j];
		}

		average /= 6; //Get actual average.

		//If average is better than the highest average.
		if (average > highestAverage)
		{
			//Then make the current student the highest scoring one.
			highest = &students[i]; //Pointer to student at i.
			//Update highest average.
			highestAverage = average;
		}
	}
	//Done!
	return highest;
}

//Input in question is 41 students.
