Question

c++ I need help!

create Student.h

In this class, you are provided with a class skeleton for the Student type. This type should contain two member variables:

• a string called name
• a vector of doubles called grades

Additionally, you should declare the following functions:

• A constructor which accepts a single string parameter called name
• A void function, addGrade which accepts a single double parameter and adds it to the grades vector
• A function which accepts no parameters and returns the student's average (Assume that all grades are weighted equally).
• A void function which prints the user to the console. The format should be:

Student.h

#include<bits/stdc++.h>
using namespace std;
#ifndef STUDENT_H
#define STUDENT_H

class Student{
   private:
       string name;
       vector<double> grades;
   public:
       Student(string x);
       void addGrade(double grade);
       double average();
       void print();
};
#endif

Student.cpp

#include<bits/stdc++.h>
#include "Student.h"
using namespace std;
Student::Student(string x)
{
   name=x;
}
void Student::addGrade(double grade)
{
   grades.push_back(grade);
}
double Student::average()
{
   int n=grades.size();
   double sum=0;
   for(int i=0;i<n;i++)
   sum+=grades[i];
   return sum/(n*1.0);
}
void Student::print()
{
   cout<<"( "<<name<<", "<<average()<<" )"<<endl;
}
