为了更好的学习这门课程，我不仅课上认真听讲，课下也努力学习，为此还在自己的电脑上安装了Ubuntu系统。

再次，Linux是用C语言编写的，我们有学习C语言的基础，读程序和编写代码方面存在的困难小一点，也是我们能较快掌握的原因之一。?

把这个问题放在其他Linux社区请求帮助也是一种选择。如果Linux得不到答案，请不要以为我们觉得无法帮助你。有时只是看到你问题的人不知道答案罢了。这时换一个社区是不错的选择。

期间我阅读了不少关于Linux的相关资料，其中也不乏一些有趣的小故事，这既丰富了我的课余生活，也让我加深了对一些术语的理解，比玩游戏强多了。?

得到到草率的回答或者根本得不到任何Linux答案。越表现出在寻求帮助前为解决问题付出的努力，你越能得到实质性的帮助。

编程学习及开发，Linux是免费，开源的操作系统，并且可开发工具相当多，如果您支持自由软件，一定要同广大热爱自由软件人士一同为其不懈努力。
