3. 有一个C++工程,里面有10个头文件(名字分别为1.h, 2.h, 3.h, 4.h…)和6个源文件(名为a.cpp, b.cpp, c.cpp…)。rna) 在Linux下,请写一个makefile文件,用于编译该工程 //题目没有文件依赖关系,不会写rnb) 如果要分别生成Release和Debug版本,该makefile如何编写rnc) 如果该工程需要跨平台(Linux/windows),但是该工程使用了一些不同环境的API(例如多线程函数),你应该如何处理?rn4. 简述下面三个函数声明有何差别。rnvoid Foo1(char str[10]) … rnvoid Foo2(char str[100]) …rnvoid Foo3(char *str) …rn这个是不是可以回答在传参时没有任何区别,使用数组给人的语义更加明确rn5. 某应用程序使用TCP协议与服务器进行通信。现在该程序出现了问题,不再往服务器发送/接受数据,你需要检查其与服务器的TCP连接状况。你应该使用什么工具/命令?常用的TCP连接状态有哪些?rn6. 有一个待优化的服务端程序,每当一个tcp连接建立后,就创建一个线程进行业务处理,一般情况下,业务处理占用较少的系统资源,并能快速完成,之后销毁该线程。但在实际运行中,该程序的执行效率低于预期(why?),而且当业务符合达到一定水平后,系统性能急剧下滑。你认为应如何优化该服务端程序?rn7. 请画出一个你熟悉的、至少包括4个状态的状态机图(最好是之前的项目或现实生活中的模型),并进行简要说明。rn8. 现需要在跨平台环境中开发一个需访问数据库的网页应用,如何避免中文乱码的问题?有什么好方法及原则来杜绝你的项目中出现乱码呢?rn9. 淘宝网上每个商品都有最近的销售记录,现需要跟踪并分析某个产品的各商家的历史销售记录,能否由程序来抓取淘宝网上的这些数据?你打算如何做?(描述出你计划使用的语言或工具、思路及想法,不必写出完整的源代码)rn10. 用XPATH(http://www.w3.org/TR/xpath/)实现一个跟踪Apple Online Store上某款iPhone 4S(如黑色16G)的“预计发货时间”变化的伪代码。rn11. 你对SQL语句的性能优化有何经验?有哪些优化方法和手段?rn12. 请写一个shell脚本来监测Linux服务器的运行状态,该脚本每天定时自动运行,采集该服务器的cpu负荷、内存或磁盘等信息,并将这些信息分别格式化输出到不同的日志文件中。rn13. 用lex/yacc(或类似工具)实现一个四则(加减乘除)运算的计算器,能够支持类似“234-(56+26)/(23+23*5)”的计算。rnrnrn求指教
