Question 3 and 4

The following code contains a memory leak.

• What constitutes that leak?

• What would be a fix to the problem?

#include <vector>

class Object

{

public:

Object(int id) : _id(id) {}

int id() const { return _id; }

private:

int _id;

};

class ObjectContainer

{

public:

void add_object(Object* o) { _container.push_back(o); } private:

using _Container = std::vector<Object*>;

_Container _container;

};

int main()

{

ObjectContainer container;

Object* o = new Object(666);

container.add_object(o);

return 0;

}

The following code fragment contains a bug. What is the bug? Describe it.

#include <vector>

#include <iostream>

int main()

{

std::vector<int> my_vector = { 1,2,3 };

std::cout << my_vector[3] << std::endl;

return 0;

}
