A structure in programming, specifically in languages like C and C++, is a user-defined data type that allows the combination of data items of different kinds. Whereas, a union, also used in these languages, stores different data types in the same memory location. 7 Structures allocate separat...

An anonymous union creates two bytes (16 bits) of memory foritoh()to access. The statementnum = nstores the number we pass toitoh()into memory as ashort, and thecoutstatements access the same bytes of memory as characters. We use a 4-bit right shift (>> 4) to access the high nibb...

It surely helped that his school had no computers, so he wasted no time in transferring to a university that did. His brother David says that it also helped that he would then be able to get into the student union bars. Oxford, 1987–1991 After Edinburgh, Alan and I wound up together...
联合(union)是一种节省空间的特殊的类,一个 union 可以有多个数据成员,但是在任意时刻只有一个数据成员可以有值。当某个成员被赋值后其他成员变为未定义状态。联合有如下特点:默认访问控制符为 public 可以含有构造函数、析构函数 不能含有引用类型的成员 不能继承自其他类,不能作为基类 不能含有虚函数 匿名union...
