Class Heap And Stack Initialisation

Given the following class

#pragma once
#include <cstdlib>
#include <stdlib.h>
#include <iostream>
#include "./baseEntity.h"

template<typename T>
class Entity : public BaseEntity {
    int id;
    T value;

public:
    Entity();
    Entity(T value);
    void info() const override;
};

#include "entity.tpp"

#include "../db/entity.h"
#include <string>
class Book: public Entity<std::string> {
public:
    Book(std::string name): Entity<std::string>(name){ 

    };
};

For heap initialisation, we have 2 ways

Stack initialisation

For stack initialisation, memory might be overwritten at any point

Book book("C++ 20 Reference");

Next however the pointer of this book (&book) might not persist and lose

Heap initialisation

If you prefer to use heap, we can do one with new

Book* book = new Book("C++ 20 Reference");

book now will be the pointer reference and will persist through the program
