While loop help

CPSC23 (2)
My instructor asked: Your job is to create a program that takes, from keyboard input:

1. The number of students in the class
2. number of points for an assignment
3. grades for the class.

You will average the grades and figure out how much of a curve should be applied for the average class score to be at least 70%. A curve should never be negative. Therefore if the calculation of the curve is negative, the curve will be 0.

So far this is what I have:

  #include<iostream>
using namespace std;

int main() 
{
	int Points;  //Number of Points student scored on assignment
	int Total; //Individual student percentage grade
	int avgTotal; //combined total of student percentage
	int pointsPossible; //Amount of points possible on assignment
	int avgClass; //Average of all classmates grades combined
	int Curve; //Computes the amount necessary for curve
	int curvedGrade; //Applied to class averages less than 70%
	int Students = 0; //Number of students within class
	int studentNumber; //Identifies each student by number
	int n = 0;

	cout << "Enter the number of students in class : "; //How many students are in the class
	cin >> Students;

	studentNumber = n + 1; //current student on list

	cout << "How many points possible in assignment : ";
	cin >> pointsPossible;

	while (studentNumber <= Students) {
		

		cout << "Enter points for student number " << studentNumber << " : "; //how many points did this student score
		cin >> Points;

		Total = (Points / pointsPossible); //calculates percentage for student grade

		avgTotal = (avgTotal + Total); //Keeps running total of all student grades

		avgClass = (avgTotal / Students); //calculates average grade of entire class

		cout << "The average grade for this class is " << avgTotal;

		if (avgClass >= 70) {
			cout << avgClass; //if class average is above 70% no curve applies
		}
		else {
			Curve = 70 - avgClass;
			curvedGrade = avgClass + Curve; //if class average is below 70% curve applies

			cout << curvedGrade;
		}
	}
	return 0;
}


Problems i'm having:
1. Can't get program to loop
2. Doesn't compute from Total calculation on down.

I don't know what I'm doing wrong.
