问题 单项选择题

下列关于链式存储的叙述中,正确的是( )。

A.链式存储结构的空间不可以是不连续的

B.数据节点的存储顺序与数据元素之间的逻辑关系必须一致

C.链式存储方式只可用于线性结构

D.链式存储也可用于非线性结构

答案

参考答案:D

解析: 链式存储结构不同于顺序存储结构,它的存储空间可以是不连续的,并且数据节点的存储顺序与数据元素之间的逻辑关系可以不一致,数据元素之间的逻辑关系是由指针域来确定的。链式存储方式可用于线性结构链式存储也可用于非线性结构,在表示复杂的非线性结构时,指针域的个数要多一些。

Shenzhen's fast development has made it become China's most crowded city! There are about 15 million people living on its 1991square kilometers. On each square kilometer averagely live 7500 people. It is 1080 more than that in Hong Kong, and nearly 800 more than that in Guangzhou.
