在C语言中,结构体是种复合数据类型,其构成元素既可以是基本数据类型(如int、long、float等)的变量,也可以是一些复合数据类型(如数组、结构体、联合等)的数据单元。编译器为结构体的每个成员按照其自然边界(alignment)分配空间。各成员按照它们被声明的顺序在内存中顺序存储,第一个成员的地址和整个结构的地址相同。 ...

Size of struct B: 24 Size of object b: 24 In the above structure, we find that the size is 24 Bytes though the same data members have been used. This is due to the change in the order of the member declaration. In this case, the alignment and padding would be like below: ...
Bit fields defined asintare treated assigned. A Microsoft extension to the ANSI C standard allowscharandlongtypes (bothsignedandunsigned) for bit fields. Unnamed bit fields with base typelong,short, orchar(signedorunsigned) force alignment to a boundary appropriate to the base type. ...
What is the alignment of a struct member with 64-bit pointers? What is the difference between _T and L? What is the difference between native api and win32 api? What is the difference of safe_cast, static_cast & dynamic_cast? What is the equivalent of C# #region in C++ what is thi...
