Quesion: My question arises from one of my c++ exercises (from Programming Abstraction in C++, 2012 version, Exercise 12.2). Here it is: void strcpy(char *dst, char *src) { while (*dst++ = *src++); } The definition of strcpy is dangerous. The danger…

METHOD 1: Consider the case where we do not know the number of elements in each row at compile time, i.e. both the number of rows and number of columns must be determined at run time. One way of doing this would be to create an array of pointers to t…

引言:说到动态申请(Dynamic Allocation)内存的好处,学过C/C++的人可能都有体会.运行时的灵活申请自然要比编码时的猜测好的多.而在内存受限情况下这种灵活性又有特别的好处--能让我们把有限的内存用的更充分.所以Keil给我们实现了一个简捷的版本,也就是这里所记录的内容. 最近翻看Kei安装目录,无意中发现C51\LIB下的几个.C文件: CALLOC.C FREE.C INIT_MEM.C MALLOC.C REALLOC.C 看到 MALLOC.C 和 FREE.C 想到可能…

Memory management is the act of managing computer memory. The essential requirement of memory management is to provide ways to dynamically allocate portions of memory to programs at their request, and free it for reuse when no longer needed. This is…

一.简介 在通过 dynamic 类型实现的操作中,该类型的作用是绕过编译时类型检查, 改为在运行时解析这些操作. dynamic 类型简化了对 COM API(例如 Office Automation API).动态 API(例如 IronPython 库)和 HTML 文档对象模型 (DOM) 的访问. 在大多数情况下,dynamic 类型与 object 类型的行为是一样的. 但是,不会用编译器对包含 dynamic 类型表达式的操作进行解析或类型检查. 编译器将有关该操作信息打包在一起,…

对于用户没有定义dctor(包括其所有成员)的类来说, new CLASS[n] 可能会直接请求sizeof(CLASS)*n的空间. 而带有dctor的 类, 因为delete[]的时候要逐个调用析构函数, 要保证调用n次析构. C++标准没有指定如何具体处理这种情况. 而对于很多数编译器来说, 是在请求的内存前面, 保存对象的个数n(放在其头部). sizeof(int)  sizeof(CLASS)  ...       n Object[0] Object[1] Object[2] ..…

ACE_INET_Addr类,在这个ACE_网络框架中,应该是比较重要的辅助类,该类主要封装了C SOCKET 的地址对象,通过外观封装的模式,把struct sockaddr_in封装在内.方便用户的操作. 因此个人认为掌握此类的常用构造方法和常用的成员函数,并深刻的理解,对于后续的学习ACE或者开发ACE网络应用程序应该会起到很大的帮助.工欲用其器.必先利其器.就先让我们把ACE_INET_Addr对象深刻的牢记在心中吧. /* -*- C++ -*- */ //==============…
