auto in C++ is the same as var in C#. Auto keyword is defined in upcoming C++ standard C++0x
The news is, that latest Microsoft Visual Studio C++ 2010 have support for this keyword. auto keyword has a new meaning – ‘declares a variable whose type is deduced from the initialization expression in its declaration’.
std::vector::const_iterator iterator = intArray.begin();
auto iterator = intArray.begin();
As you see, ‘std::vector::const_iterator iterator’ becomes ‘auto iterator’. No more unnecessary typing.
The same concept in C# is available from version 3.0. Variables that are declared at method scope can have an implicit type var. An implicitly typed local variable is strongly typed just as if you had declared the type yourself, but the compiler determines the type. Reference.
P.S. Open source world are using auto keyword for at least a year. Support for auto keyword was added to GCC beginning from version 4.4.0
It seems that _SECURE_SCL_THROWS is deprecated in Visual Studio C++ 2010. Because include file ‘Microsoft Visual Studio 10.0\VC\include\yvals.h’ has the following code block:
#pragma _CRT_WARNING( _DEPRECATE_SECURE_SCL_THROWS )
It gets undefined, and if you search c++ header files, there are no references to _SECURE_SCL_THROWS anymore. The strange part is, that latest documentation still have reference to _SECURE_SCL_THROWS, which states that it is valid macro, and ‘Defines whether incorrect use of Checked Iterators causes an exception or a program termination’.
The good news is, that _SECURE_SCL is enabled by default, that causes _ITERATOR_DEBUG_LEVEL to be enabled, that causes iterators to break program debug version if you do something wrong with stl iterators.
Visual Studio 2008 Pro does not ship with native profiler. Only Team edition does.
Sleepy is a C/C++ CPU profiler for Windows systems.
Very Sleepy is improved version with Threading support and much more.
