What does almost C++11 mean?
C++11 is a version of the ISO/IEC 14882 standard for the C++ programming language. Areas of the core language that were significantly improved include multithreading support, generic programming support, uniform initialization, and performance.
When did C++11 come out?
2011
In 1998, C++98 was released, standardizing the language, and a minor update (C++03) was released in 2003. After C++98, C++ evolved relatively slowly until, in 2011, the C++11 standard was released, adding numerous new features, enlarging the standard library further, and providing more facilities to C++ programmers.
What is C++ 98 and C++11?
New Smart Pointer Classes C++98 defined only one smart pointer class, auto_ptr , which is now deprecated. C++11 includes new smart pointer classes: shared_ptr and the recently-added unique_ptr.
What is direct initialisation of an array?
When we directly provide the elements of an array during its initialization/declaration is called direct initialization of an Array in Java. For Example – int[ ] numbers = {1, 2, 3, 4, 5};
How does uniform initialization work in C + + 11?
Uniform Initialization expands on the Initializer List syntax, to provide a syntax that allows for fully uniform type initialization that works on any object – removing the distinction between initialization of aggregate + non-aggregate classes, arrays, STL/custom collection classes, and PODs. Thus, where we previously had to choose between:
Is the uniform initialization a replacement for the old style?
If CoolStringType happens to have a constructor which takes a const char* and a size_t (just like std::string does) then the call to DoSomething ( {strValue, strLen}) will result in an ambiguity error. No, Uniform Initialization should not be thought of as a replacement for the old style constructor syntax.
Is the initializer list the same syntax as uniform initialization?
Initializer lists use the same syntax as uniform initialization. So there have to be some rules to explain what to do in the case of ambiguity. The rule is pretty simple: if the compiler can use an initializer list constructor with a brace-initialized list, then it will.
What is the purpose of uniform initialization in Java?
Uniform Initialization. Uniform Initialization expands on the Initializer List syntax, to provide a syntax that allows for fully uniform type initialization that works on any object – removing the distinction between initialization of aggregate + non-aggregate classes, arrays, STL/custom collection classes, and PODs.
