'''auto_ptr''' is a [[Template (programming) | template]] class available in the [[C_plus_plus|C++]] [[C Plus Plus standard library | Standard Library]] (declared in '''<memory>''') that provides some basic [[Resource Acquisition Is Initialization | RAII]] features for [[Pointers#C.2FC.2B.2B | C++ raw pointers]].

The broad objectives of the '''Business and Economics [[Wikipedia:WikiProjects|Wikiproject]]''' is to expand the coverage and content of articles related to [[Business]] and [[Economics]]. More specifically, we need to have more business and economics related [[WP:FA|Featured articles]] and more regular coverage for business and economics news in [[current events]].

== Definition ==

The scope of this project is to provide guidelines on topics related to [[Business]] and [[Economics]] and provide a space, where users can collaborate to improve related articles.

The auto_ptr class is defined in [[ISO/IEC 14882]], section 20.4.5 as:

== Projects ==

* [[Wikipedia:Companies, corporations and economic information|Companies, corporations and economic information]]

* [[Wikipedia:WikiProject Numismatics|Numismatics]]

* [[Wikipedia:WikiProject Game theory|Game theory]]

* [[Wikipedia:WikiProject Deletion sorting/Business]]

namespace std {

==Participants==

* pamri

template <class Y> struct auto_ptr_ref {};

* Saksham

template<class X>

class auto_ptr {

public:

typedef X element_type;

// 20.4.5.1 construct/copy/destroy:

explicit auto_ptr(X* p =0) throw();

auto_ptr(auto_ptr&) throw();

template<class Y> auto_ptr(auto_ptr<Y>&) throw();

auto_ptr& operator=(auto_ptr&) throw();

template<class Y> auto_ptr& operator=(auto_ptr<Y>&) throw();

auto_ptr& operator=(auto_ptr_ref<X> r) throw();

~auto_ptr() throw();

// 20.4.5.2 members:

X& operator*() const throw();

X* operator->() const throw();

X* get() const throw();

X* release() throw();

void reset(X* p =0) throw();

// 20.4.5.3 conversions:

auto_ptr(auto_ptr_ref<X>) throw();

template<class Y> operator auto_ptr_ref<Y>() throw();

template<class Y> operator auto_ptr<Y>() throw();

};

}

==Structure==

== Semantics ==

<!--

Discuss the format for each article based on the WikiProject. Include various categories applicable to the topic.

-->

The auto_ptr has semantics of strict ownership, meaning that the auto_ptr instance is the sole responsible for the object's life-time. If an auto_ptr is copied, the source loses the reference. For example:

==Goals==

# Create templates & guidelines for topics on Economic Indicators and National economies.

int *i = new int;

<!--This section is for organizing group projects-->

auto_ptr<int> x(i);

==Tasks==

auto_ptr<int> y;

{{Bizetasks}}

y = x;

cout << x.get() << endl;

cout << y.get() << endl;

This code will print a [[Null (Computer) | NULL]] reference for the first auto_ptr object and some address for the second, showing that the source object lost the reference during the assignment (''=''). The raw pointer ''i'' in the example should not be deleted, as it will be deleted by the auto_ptr that owns the reference.

==Adopt an article==

Similar to the [[Wikipedia:Collaboration of the week|Collaboration of the week]], but on a smaller scale, you might want to "adopt" an article. This would involve doing the research, writing, and picture-taking (if possible) for either a non-existent article or a stub. Of course, everyone else can still edit an adopted article, and you can work on other things too, but the idea is to find a focus for a while, to try and build up the number of quality articles the Project has produced.

* [[Example|Example article]]: [[User:Example]]

<!--Check [[Wikipedia:WikiProject Melbourne#Adopt an article]] to see how this section is used.-->

Notice that the object pointed by an auto_ptr is destructed using ''operator delete''; this means that you should only use auto_ptr for pointers obtained with ''operator new''. This excludes pointers returned by [[malloc|malloc/calloc/realloc]] and ''operator new[]''.
