Классы и структуры С++

[ge4r]

День добрый
Нужны несколько подсказок\направляющих толчков и тп

#include "stdafx.h"

struct Student
{
    char* Name;
    double MeanMark;
    int Group;
};

class CStudentList
{
public:
    void AddTail (const Student& src);
    void AddHead (constStudent& src);
    int GetCount () const;
    void InsertAt (int nIndex,const Student& src);
    void RemoveAt (int nIndex);
    Student GetAt (int nIndex) const;
};



int _tmain(int argc, _TCHAR* argv[])
{
     
    return 0;
}

вот,описал структуру студент и класс

теперь вопросы:
методы описываются как и в паскале, просто процедурами функциями?
как в спп работать с динамической структурой данных...точнее интересует синтаксис,ибо с указателями и дин.массивами уже работа

методы описываются как и в паскале, просто процедурами функциями?

В С++ нет процедур, только функции, хотя функция которая не возвращает значение в какой-то мере пародия на процедуру.

как в спп работать с динамической структурой данных...точнее интересует синтаксис,ибо с указателями и дин.массивами уже работа

Ну например выделяем память для указателя на структуру

Student *stud=new Student;
...
delete stud;

Или для указателя на объек класса CStudentList

CStudentList *stud=new CStudentList;
...
delete stud;

спс,буду пробовать...)

помогите,пожалуйста найти косяк...он где-то в функции ремув
