Introduction

C++0X is a new standard who will replace the C++98 and C++03 from the ISO/IEC 14882


Motivation

• Add new features to the language • Improve c++ to make easier the design of systems

• Increase security of data and improve old techniques

• Increase the hability of working directly with hardware and

performance


Motivation

• Make c++ easier to understand but robust at the same time • Improve the core of the language


Improvements

• Garbage collector • Extern template

extern template class std::vector<MyClass>; libraries:• Hash Tables • Regular Expressions • General Purpose Smart Pointers • Extensible Random Number Facility • Mathematical Special Functions


Improvements

• Concepts Container, Predicate..

• Range-based for-loopo int my_array[5] = {1, 2, 3, 4, 5}; for(int& x : my_array) { x *= 2; }


Improvements

• Lambda Function [ ](int x, int y) { return x + y; }

std::for_each(some_list.begin(), some_list.end(), [&total](int x)) { total += x;}

• Object construction

class SomeType { int number; public: SomeType(int new_number) : number(new_number) {} SomeType() : SomeType(42) {} };


Unrestricted unions

struct Point { Point() {} Point(int x, int y): x_(x), y_(y) {} int x_, y_; }; union U { int z; double w; Point p; U() { new( &p ) Point(); }

};


New string literals

u8"I'm a UTF-8 string." u"This is a UTF-16 string." U"This is a UTF-32 string."Type long long int

Static assertionsstatic_assert ((3.14 < GREEKPI) && (GREEKPI < 3.15), "GREEKPI is inaccurate!");

sizeof

struct SomeType { OtherType member; }; sizeof(SomeType::member)


Default and deletestruct NonCopyable { NonCopyable & operator=(const NonCopyable&) = delete; NonCopyable(const NonCopyable&) = delete; NonCopyable() = default; };Thread-local storage

Multitasking memory model


Conclusions

• C++0X looks for a friendly environment for beginners • This standard is still incomplete and we expect more news

about it • It adds new tools and options to improve the design of

systems• C++0X Also accept sintax that in previous standards could

show errors
