Chapter 4 Data Structure 4.1 An Introduction to Data Structures Abstraction Data structures provide a more understandable way to look at data; thus, they offer a level of abstraction in solving problems. For example, by storing data in a stack, we can focus on things that we do with stacks, such as pushing and popping elements, rather than the details of how to implement each operation. In other words, data structures let us talk about programs in a less programmatic way. 抽象化 数据结构提供一个更好理解的方法查看数据;因此,它们在解决问题中提供 定的抽象化水平。例如,通过把数据储存在堆栈中,我们可以将重点集中 在对堆栈的操作上,如使元素进栈和出栈,而不是集中在实现操作的细节上。 换句话说,数据结构使我们以较少的编程方式谈论程序。 计算机专些英语 4-7Chapter 4 Data Structure 计算机专业英语 4-7 Abstraction Data structures provide a more understandable way to look at data; thus, they offer a level of abstraction in solving problems.
