这章主题为结构休,但是包括 Structures, Unions, Bit-Fields 等内容,其实这些类型都可以算是一种结构化数据类型,将不同的类型组合到一起。 联合体 union 允许在同一内存地址上存取不同的类型,将各种类型定义在联合体中就是实现这样一个功能的。 以下示范使用 union 类型: // declares an union number typeunionn...
much like functions encapsulate program statements. Unions are like structures, but data members overlay (share) memory, and unions may access members as different types. We use structures and unions in applications that need user-defined types, such...
Anonymous Structures and Unions in C - The feature of anonymous structures and unions was introduced in C11 standard. The aim was to enhance the flexibility of C and also to discard the need of superfluous naming in certain cases.
In C, structures and unions can hold integer values of defined bit widths. So instead of holding 32 bits, you can define anintstructure member that holds only 4 bits. Weird. This capability is something I’ve never seen used and is perhaps one of the most unusual aspects of C. It’s ...

at each vertex sort edges by weight and include edge in MST if it dosen't form a cycle with the edges already taken (using set unions) repeat until there are V-1 edges Prim's Algorithm O(ElogV) at each vertex add a 2nd vertex connected to the first through a minimum weight edge an...
where inobj1, the member'a'has the value 01, the 34 78 32 sequence is padding bytes with unspecified values and 0C000000 is the value of the member'b'. Inobj2, the value of'a'and'b'are the same but because the value of padding is unspecified which is right now 34 AA CC. ...
