Pointer variables, simply called pointers Holding memory addresses as their values A kind of data type Normally, a variable contains a specific value, e.g., an integer, a floating-point value However, a pointer contains the memory address of a variable that in turn contains a specific value....
hierarchical databases, which provide single links between sets of records at different levels, network databases create multiple linkages between sets by placing links, or pointers, to one set of records in another; the speed and versatility of network databases have led to their wide use in ...
Strict rules on assignments to or from memory areas keep you from creating dangling pointers, and thus maintain Java’s pointer safety. Objects allocated in memory areas may contain references to objects in the heap. Thus, the garbage collector must be able to scan memory outside the heap for...

11、 make a data structure store data of any type by using void pointers to the data rather than by maintaining private copies of the data in the data structure itself.复用性:因为数据结构趋向于模块化并和环境无关,所以数据结构是可以复用的。因为每种结构有一个预定的接口,通过该接口限制访问存储在...
