[2004.优快云.04.10][特别策划]昨天,我的大学学习

博客涉及嵌入式操作系统、数据结构和算法等信息技术领域内容,虽未给出具体内容,但从标签可知围绕这些关键方面展开,忽略了生活等无关信息。

昨天,我的大学学习
引言

2000年9月5日迷茫中的我开始了大学生活,2004年7月7日我结束了4年的本科生活。时光如流水,人常说大学四 年光阴是人生中最重要的四年,对于我来说这四年如此的漫长,但又如此短暂,似乎是一个结束,却又意味着一段更 为令人激动的生活的开始。按照惯例,总要记些文字下来的。总结过去,给自己一个交待。展望未来,给自己一点希 望。同时也希望这些文字能够对刚刚步入大学学习的师弟师妹们有一个参考作用,需要提醒大家的是,我的大学生活 并非仅仅属于我自己,他可能代表了包括你在内的一些人即将的经历,人常说“尽量吸取别人的教训,因为你没有时 间将世界上所有的错误都犯一遍”。取其精华,弃其糟粕。倘若在你的大学学习中能够有些许帮助,也就不枉一记 了?? 文章分为若干节完成,分别记载我的大学一年级到四年级学习和生活。最后给出一个对初学者的建议和对我自己 未来学习的期望。由于学业繁忙,每篇文章仅记录了部分大学学习体会,文字零散不成规律,还望读者海涵。
