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

// 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 students in class? ";     int classsize;     cin >> classsize;      (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();     ( 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 declare class called creategradebook inside student.hand define in student.cpp , put code of main.cpp in it. in other words want main.cpp still there no codes in below;

#include <iostream>  using namespace std;  int main() { } 

please tolerant if question inappropriate or off topic i'm new stackoverflow. i've read faq section not of it.

well here's start

class creategradebook { public:     void fillvector();     void printvector() const; private:     vector<student> myclass; }; 

notice how vector declared in main has become private data member myclass. 2 functions declared have become public methods of creategradebook. notice have lost parameters instead they'll operate on private data member myclass.

i'll leave rest.
