Unions have the same formats and operators as structures. Unlike structures, which reserve separate chunks of memory for each data member, unions allocate only enough memory to accommodate the largest data member. On 16-bit and 32-bit machines, for example, the definition union jack { long numb...

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 ...
Accessing Structure Members 2/23/2019 Accessing Structure Members We can't directly judge whether 2 structure variables are same or not, and we must compare each member. struct student { int num; char name[20]; } stu1, stu2 = {101, "Jack"}; stu1 = stu2; if ( stu1 == stu2 ) ...

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: ...
