Getting Median From Array

[bender]

I am trying to get a median from an array of which i do now know how many items are in it. I know I have to sort it, but I do not how to do this to get the median. Here is what I have so far. How do i go about finding the median?

  int howmany;
	int sum = 0;
	int grades[100];

	cout << "How many grades do you have for Exam 2?"; cout << endl;
	cin >> howmany;
	cout << "Please enter the grades for Exam 2"; cout << endl;

	for (int i = 0; i < howmany; ++i){
		cout << "Enter Grade " << i + 1 << ": ";
		cin >> grades[i];
		sum += grades[i];
	}   // End For
