Q: 我应该怎样处理内存泄漏? A: 很简单,只要写“不漏”的代码就完事了啊。显然,如果你的代码到处是new、delete、指针运算,那你想让它“不漏”都难。不管你有多么小心谨慎,君为人,非神也,错误在所难免。最终你会被自己越来越复杂的代码逼疯的——你将投身于与内存泄漏的奋斗之中,对bug们不离不弃,直至山峰没有棱角,地球不再转动。而能让你避免这样困境的技巧也不复杂:你只要倚重隐含在幕后的分配机制——构造和析构,让C++的强大的类系统来助你一臂之力就OK了。标准库中的那些容器就是很好的实例。它们让你不必化费大量的时间精力也能轻松惬意地管理内存。我们来看看下面的示例代码——设想一下,如果没有了string和vector,世界将会怎样?如果不用它们,你能第一次就写出毫无内存错误的同样功能代码吗?

在本光盘中提供了由谭浩强编著的《C++程序设计》(清华大学出版社出版)一书中各章的例题程序以及全部习题的参考解答,以方便教师进行教学,也便于读者上机运行这些程序以及在此基础上修改和调试程序。 程序按章设立文件夹(子目录),例如文件夹c12中包含的是第12章全部例题的程序。程序的文件名以c开头,与例题号一一对应,如c5-7.cpp是第5章例5.7的程序。对于教材中同一例题中包含两个或多个程序的,在文件名中加了顺序号,如c10-4-1.cpp是例10.4的第1个程序,c10-4-2.cpp是例10.4的第2个程序。 教材中所有的程序都是符合C++标准规定的,在GCC中能通过,但有的程序在Visual C++ 6.0中通不过。如果在Visual C++ 6.0环境下运行程序,需要对程序作一些修改。例如,如果程序c10-4-1.cpp在Visual C++ 6.0环境下编译,第1行应改为“include <iostream.h>”,并将第2行“using namespace std ”取消即可顺利通过编译,其他类似。我们在教材的例题程序中还提供了能在Visual C++ 6.0环境下运行的程序,在文件名中加了"(VC)"字样,如c10-4-2(VC) 表示它是对程序c10-4-2修改后能用于Visual C++ 6.0环境的程序。
