How to run below codes inside the Student.cpp through a class? - c++

Question

// main.cpp
#include <iostream>
#include <vector>
#include <string>
#include "Student.h"
using namespace std;
void fillVector(vector<Student>&);
void printVector(const vector<Student>&);
int main()
{
vector<Student> myClass;
fillVector(myClass);
printVector(myClass);
return 0;
}
void fillVector(vector<Student>& newMyClass)
{
string name;
char grade;
cout << "How many you students are in your class? ";
int classSize;
cin >> classSize;
for (int i=0; i<classSize; i++)
{
cout<<"Enter student name: ";
cin>>name;
cout<<"Enter student grade: ";
cin>>grade;
Student newStudent(name, grade);
newMyClass.push_back(newStudent);
cout<<endl;
}
cout<<endl;
}
void printVector(const vector<Student>& newMyClass)
{
int size = newMyClass.size();
for ( int i=0; i<size; i++ )
{
cout<<"Student name: "<<newMyClass[i].getName()<<endl;
cout<<"Student grade: "<<newMyClass[i].getGrade()<<endl;
cout<<endl;
}
}
// Student.h
#ifndef STUDENT_H_INCLUDED
#define STUDENT_H_INCLUDED
#include <iostream>
#include <string>
using namespace std;
class Student
{
public:
Student();
Student(string, char);
~Student();
string getName() const;
char getGrade() const;
void setName(string);
void setGrade(char);
private:
string newName;
char newGrade;
};
#endif // STUDENT_H_INCLUDED
// Student.cpp
#include "Student.h"
Student::Student()
{
newGrade = ' ';
}
Student::Student(string name, char grade)
{
newName = name;
newGrade = grade;
}
Student::~Student() {}
string Student::getName() const
{
return newName;
}
char Student::getGrade() const
{
return newGrade;
}
void Student::setName(string name)
{
newName = name;
}
void Student::setGrade(char grade)
{
newGrade = grade;
}
My aim is to declare a class called CreateGradeBook inside Student.hand define it in Student.cpp and put all the code of the main.cpp in it. In other words I want main.cpp to be still there but with no codes in it like below;
#include <iostream>
using namespace std;
int main()
{
}
Please be tolerant if my question is inappropriate or off topic as I'm fairly new with StackOverflow. I've read FAQ section but not all of it.

Answer 1

Well here's a start
class CreateGradeBook
{
public:
void fillVector();
void printVector() const;
private:
vector<Student> myClass;
};
Notice how the vector you declared in main has become a private data member myClass. The two functions you declared have become public methods of CreateGradeBook. Notice also that they have lost their parameters instead they'll now operate on the private data member myClass.
I'll leave you to do the rest.
