Programming abstractions in C阅读笔记:p91-p106

《Programming Abstractions In C》学习第45天,p91-p102,完成第二章内容学习。总结如下:
一、技术总结

1.垃圾回收
p91,"Some language, including Java support a system for dynamic allocation that actively goes through to see what parts of it are used,freeing any storage that is no longer needed. This strategy is called garbage collection."垃圾回收是一种“策略”——主动的去遍历动态分配的内存,释放不再使用的内存。

二、英语总结
1.streamline什么意思?
答:vt. improve the effectiveness of an organization, often by making the way that activities are performed simpler.(精简)

2.in preference to什么意思?
答:instead of/rather than(而不是),所以词组里面包含preference(偏爱),但是to后面跟的被对比的内容,是否定的。

3.bother to什么意思?
答:make the effort to do sth,费心,努力。
三、关于习题
个人偏向于在工程中阅读代码,而不是通过做题。看书是为了掌握理论,了解技术全貌,使知识系统化,所以个人采取的方式是每章随机选一题完成,检验学习的效果,其它题目跳过。
