Why isn't sizeof for a struct equal to the sum of sizeof of each member?
...) (like structure Z in the example above).
IMPORTANT NOTE: Both the C and C++ standards state that structure alignment is implementation-defined. Therefore each compiler may choose to align data differently, resulting in different and incompatible data layouts. For this reason, when dealing with ...
What's the point of g++ -Wreorder?

Difference between passing array and array pointer into function in C
... There is a difference when using (at least some older) MSVC C++ compilers, due to the compiler incorrectly mangling the function name differently in the two cases (while recognizing that they are the same otherwise), resulting in link problems. See "Won't fix" bug report here connect....

Transfer of ownership cannot really be implemented in C++ currently, because there are no means to transfer something from one object to another supported by the language: If you try to return an object from a function, what is happening is that the object is copied. So a smart ...
Difference between “managed” and “unmanaged”
...pplication managed by the CLR. If you are writing an application in Visual C++ .NET you can produce managed code if you like, but it's optional.
Unmanaged Code
Unmanaged code compiles straight to machine code. So, by that definition all code compiled by traditional C/C++ compilers is 'unmanaged co...
