C++程序设计课堂教学“X+2”方法探讨

C++语言概念多,语法复杂,容易与C语言相关概念/语法混淆,为此,在C++程序设计课堂教学中提出"X+2"教学方法,并应用于教学过程中。实践证明,应用该方法进行教学后,学生能够更容易地掌握C++的语法,彻底弄清楚其与C语言相关概念/语法的区别,提高了学生学习C++程序设计课程的兴趣,改善了课堂教学效果。     

C/C++语言学习系统的构建

随着计算机技术的快速发展,大中专院校中越来越多的专业开设了C语言与C++语言的有关课程,由于它们是一门实践性很强的学科,而理论性学习不能真正的让学生掌握其有关知识,不能真正反映学生的计算机应用水平和能力。本系统是为了提高学生的知识水平及实践编程而设计的。此系统能够让学生更好、更快的掌握C/C++语言的基本知识和编程方法。

波澜不惊的C＋＋

2003年对于C++程序员来说,是波澜不惊的一年。如果用一句话来概括,可以说这一年来在C++开发领域没有发生任何标志性或者决定性的事件。总体上讲,软件产业中最活跃的应用系统开发逐渐从C++转移到以Java和C#、VB.NET为代表的新一代编程语言之上,这一趋势已经越来越明显。预期在几年之后,C++将主要成为一个系统级的开发语言,在嵌入式开发、核心系统软件开发等领域发挥作用。在美国,C++处于稳定和缓慢地发展之中,从工作需求统计和其他现实迹象来看,C++仍然是工业界最主流的语言之一,而且C++程序员的收入仍然明显高于其他语言的使用者。

PowerBuilder中的Watcom C＋＋Builder的应用

我们用PowerBuilder开发应用系统,多数可以用PowerBuilder自身提供的函数实现,但遇到图像处理、复杂的逻辑和科学运算时,单靠PowerBuilder的自身功能就有些力不从心了。如果选用C或C++语言来实现极为容易,可喜的是PowerBuilder内嵌有Watcom C++Class Builder,它是一种C++语言编译器,选用它来解决PowerBuilder自身不易实现的功能,显得十分简单,使用也较方便。

Exceptional C or C with exceptions

C does not have exception handling facilities. Errors are handled by examining the value returned by each function and signals (conditions reported to the program) are handled by using library functions. These approaches lead to ad hoc error-handling techniques and can make programs hard to understand. Exceptional C, a superset of C, provides exception handling facilities. Exceptional C integrates the two techniques used by C programmers (i.e., status values and signals) to handle errors into one unified exception handling mechanism. In this paper, I review exception handling models, specify the criteria used for designing the exception handling facilities in Exceptional C, and then describe these facilities. I also illustrate the use of the exception handling facilities with examples.     

OKI C5200／C3100

激光打印和LED打印是当今数码打印领域的两大核心技术．二者的不同之处在于光扫描成像过程。目前．普通激光打印技术的光扫描成像过程是将全部数据信号串行传送给一个光发射装置,然后发射出的光线经旋转的多棱镜反射后再成像于感光鼓上。类似于激光打印技术,LED技术的光扫描成像方式则是采用了密集LED阵列为光发射器,数据电信号经LED转化为光信号．并照射到感     

C/C++预处理分析与改进

通常的C/C 预处理器是一个宏处理器,在编译前自动地把源文件转换为编译器可识别的形式。传统的预处理方法基于文本行替换,没有考虑到具体的上下文环境。这种预处理机制在文件包含、宏作用域、头文件关系上存在着一些缺陷,会影响工程项目代码重用,降低程序的可维护性、可扩展性等。通过从分析c预处理器缺陷出发,并利用FOG[1]及其语言可以得到一种基于元变量和元函数的语法替换机制的解决方案。

High-Fidelity C/C++ Code Transformation

As software systems become increasingly massive, the advantages of automated transformation tools are clearly evident. These tools allow the machine to both reason about and manipulate high-level source code. They enable off-loading of mundane and laborious programming tasks from human developer to machine, thereby reducing cost and development timeframes.Although there has been much academic work in software transformation, there still exists many hurdles in realising this technology in a commercial domain. From our own experience, there are two significant problems that must be addressed before transformation technology can be usefully applied in a commercial setting. These are: 1.) avoiding disruption of style (i.e. layout and commenting) and the introduction of any undesired modifications which occur as a side effect of the transformation process. 2.) correct handling of C preprocessing and the presentation of a semantically correct view of the program during transformation. Many existing automated transformation tools inherently disrupt style through the use of pretty printing and the need to perform preprocessing before any transformation. Some also require source to be modified so that it conforms to a subset of the grammar. In this paper we describe our own C/C++ transformation system, Proteus, that is able to meet the stringent criteria laid out by Lucent's own software developers.     

改进C/C++的预处理功能

预处理在C/C 中发挥着重要作用,然而这些预处理功能存在着一些缺陷,例如在头文件包含进来时,无法改变头文件中的内容;代码的重用性不高;大量重复代码等等。本文提出用一种高级配置语言XVCL(XML-basedVariantConfigura-tionLanguage)代替原来的预处理机制,来克服以上提出的问题。文件被组织为树形结构,并定义了利于提高重用性的变量作用域机制。文章通过一个实例来验证本文提出的方法的有效性。

High-fidelity C/C++ code transformation

As software systems become increasingly massive, the advantages of automated transformation tools are clearly evident. These tools allow the machine to both reason about and manipulate high-level source code. They enable off-loading of mundane and laborious programming tasks from human developer to machine, thereby reducing cost and development time frames.Although there has been much work in software transformation, there still exist many hurdles in realizing this technology in a commercial domain. From our own experience, there are two significant problems that must be addressed before transformation technology can be usefully applied in a commercial setting. These are: (1) Avoiding disruption of the style (i.e., layout and commenting) of source code and the introduction of any undesired modifications that can occur as a side effect of the transformation process. (2) Correct automated handling of C preprocessing and the presentation of a semantically correct view of the program during transformation. Many existing automated transformation tools require source to be manually modified so that preprocessing constructs can be parsed. The real semantic of the program remains obscured resulting in the need for complicated analysis during transformation. Many systems also resort to pretty printing to generate transformed programs, which inherently disrupts coding style. In this paper we describe our own C/C++ transformation system, Proteus, that addresses both these issues. It has been tested on millions of lines of commercial C/C++ code and has been shown to meet the stringent criteria laid out by Lucent’s own software developers.
