Design and Implementation of an Aspect-Oriented c Programming language

PROcEEDINGS OF THE AcM ON PROGRAMMING languageS-PAcMPL 2024年第OOPSLA期8卷 642-669页

Aspect-Oriented Programming (AOP) is a programming paradigm that implements crosscutting concerns in a modular way. People have witnessed the prosperity of AOP languages for Java and c++, such as AspectJ and Aspectc++, which has propelled AOP to become an important programming paradigm with many interesting application scenarios, e.g., runtime verification. In contrast, the AOP languages for c are still poor and lack compiler support. In this paper, we design a new general-purpose and expressive aspect-oriented c programming language, namely Aclang, and implement a compiler for it, which brings fully-fledged AOP support into the c domain. We have evaluated the effectiveness and performance of our compiler against two state-of-the-art tools, Acc and Aspectc++. In terms of effectiveness, Aclang outperforms Acc and Aspectc++. In terms of performance, Aclang outperforms Acc in execution time and outperforms Aspectc++ in both execution time and memory consumption.

Based on the reflection of the research status, this study designs a value-added evaluation model that conforms to the characteristics of 'c language Programming', and completes the teaching research and practice accordingly. Through the continuous vertical comparison of students' individual progress, the value-added level of students' knowledge and skills is reasonably quantified. Through the horizontal comparison between the experimental group and the control group, the effectiveness of value-added evaluation in improving the teaching effect of 'c language Programming' is verified. It is hoped to provide model reference and practical reference for c language teachers to explore value-added evaluation and provide new ideas for improving the teaching effect of 'c language Programming'. © 2023 IEEE.

With the rapid development of electronic information technology, the performance of embedded microcontroller is constantly improved, and the software of UAV flight control system is also developing in the direction of multi-function and multi-task. Traditional flight control software is usually written in c language, resulting in its scalability and modular design is limited. In view of the relatively consistent core content of the flight control system software, object-oriented thought and component technology are introduced to carry out modular design and implementation of the core part, improve the scalability and flexibility of the system, and facilitate the rapid addition of new functions. Based on the analysis of the shortcomings of the existing flight control software design, this paper proposes to use c++ language to componentize the driver code, design each submodule in the form of classes, and build the overall software framework according to the dependence relationship of the software level. Through component technology, the design and implementation of the driving component are completed, and the design principle of the driving component is discussed, and the implementation process of the component is explained in detail through the concrete code, and the derivation relationship between the components is analyzed. The subscription-release communication mechanism based on component relationship is designed, the communication interface between modules is standardized, and the independence of each module of flight control software is improved. Based on the driver component, the design and implementation of each task thread are completed, the data interaction and synchronization relationship between the task threads are discussed in detail, and the implementation details and execution process of the task thread are analyzed in combination with specific components. The relationship between the driver component and the task is sorted out, the integration of fl

The development of soft computing methods in the late 1960s, including fuzzy system theory, grey system and rough set theory, and the rapid progress of computer science over the past few decades have together enhanced engineering analysis. The 21^(st) century has witnessed tremendous development of big data analysis. The present study implements soft computing and related computer toolboxes for big data analysis. However, simply applying soft computing method in combination with computing toolbox for data analysis can be deficient. First, the indexes for analysis are rather complex and data amount is huge as well. Second, the computing toolbox is not compatible with the applied soft computing, either. To prevent such inadequacy, this study also implements the Technique for Order Preference by Similarity to Ideal Solution for data analysis. The mathematical model of technique for order preference by similarity to ideal solution for data analysis is firstly introduced, with the disadvantages of subjective space being explained. Next, grey relational grade in the grey system is applied to transfer subjective space into objective space. c language-based computer toolbox is developed to help calculate and analyze a large amount of data on the one hand, and build up the integration of the two parts on the other. Finally, weight analysis of power harmonics conducted in the computer classroom serves to verify the rationality and accuracy of the mathematical model proposed in this paper.

Human now rely on computer programs to operate mathematical problems due to the rise of soft computing. Therefore, MATLAB had become one of the most useful software in verifying and comparing mathematical operations. However, MATLAB couldn't solve every mathematical operation in many cases, especially in the grey prediction of the grey systm theory. Other solutions need to be found when it comes to calculating the fractional power of the grey generating. It is found that by using basic combinatorial mathematics, accurate results can be reached. Therefore, the fractional power calculate matrix toolbox based on c language had been developed in order to solve the inadequacy of MATLAB. This toolbox not only simplifies the mathematical operations but also provides assistance in calculation and verification. After comparing the results, defects from the MATLAB mathematical operations in Grey Theory can be improved.

The fundamental problem of cultivating new engineering talents is ability training, and computer programming ability is an important ability of new engineering talents. In view of the difficulty of students' programming ability in c language teaching, it is necessary to implement c language teaching reform in order to train the programming ability of new engineering talents. Based on Vygotsky's theory of "proximal development zone" and constructivism learning theory, design and application of scaffolding c language teaching it is proved that the teaching of scaffolding c can make the teaching of programming ability clear, objective and and operable.

The highest share of cost for a software product is software maintenance. Identifying the quality merit of the software architecture is extremely vital as the quality directly relates to software maintenance. A good design always exhibits good quality characteristics because it is directly related to good architecture. Although c language is a major language in the software industry, few studies investigate the quality of the architecture in c language. This study aims to evaluate the quality of c language projects in a quantifiable form by focusing on dependency graphs, associated metrics, and software architecture. In particular, this study (i) formulates the architecture representation of c projects, (ii) determines the metrics capturing the quality of architecture, (iii) defines code smell and metrics relations and (iv) conducts an empirical analysis on 58 c projects. We show which metrics derived from dependency graphs can detect architectural issues and verify their relation to software architecture quality.

In order to solve the problem that the A-law 13 polyline coding algorithm lacks a specific programming language simulation, c language is used to implement the algorithm in this paper. First, the polar code is obtained according to the positive and negative sample values. Then the paragraph code and the inner code are obtained and finally decoded. Experimental results show that the program can realize A-law 13 polyline encoding and decoding, and for a given sample value, it can obtain its 8-bit encoding. compared with the bit-wise encoding method, the program is more efficient.
