#include <iomanip>
#include <ios>
#include <iostream>
#include <string>
#include <vector>
using namespace std;
int main()

string name;
cin >> name;
cout << "what's their midterm and final exam grades:";
double midterm, final;
cin >> midterm >> final;
cout << "homework grades";
vector<double> homework;
double x;
while (cin>>x)
{
homework.push_back(x);
}

int size;
size = homework.size();
