Can someone please tell me why this doesn't work?

#include<iostream>
#include<ios>
#include<algorithm>
#include<vector>
#include<string>
#include<iomanip>

using namespace std;

int main(){

    cout << "Enter the first student's name: ";
    string name1;
    cin >> name1;

    cout << "Enter the second studesnt's name: ";
    string name2;
    cin >> name2;

    cout << "Enter the 10 homework grade for the first student: ";

    vector<double> stu1;
    vector<double> stu2;
    double x;
    double y;
    double sum1 = 0;
    double sum2 = 0;

    while(cin >> x && y != 10){
        stu1.push_back(x);
        y++;
        sum1 += x;
    }


    cout << "Enter the homeworks grades for the second student: ";
    y = 0;

    while(cin >> x && y != 10){
        stu2.push_back(x);
        y++;
        sum2 += x;
    }

    streamsize prec = cout.precision();
    setprecision(3);

    cout << name1 << "'s average is: " << sum1 / 10 << endl;
    cout << name2 << "'s average is: " << sum2 / 10 << endl;
    setprecision(prec);





    return 0;
}

It's suppose to stop letting you input numbers after the 10th, but it doesn't.

(1) You didn't initialize y before asking for the grades for the first student.
(2) y is a double so the y != 10 condition will probably always be false thanks to the inaccuracy of floating point. I would recommend you make y an int instead.

Thanks, that went completely over my head.

Replace

double y;

with

int y = 0;
