How to find the C language design PAT exercises from Zhejiang University teacher Weng Kai?

To locate the C language programming exercises associated with the PAT (Programming Ability Test) and Zhejiang University teacher Weng Kai, the most direct and reliable method is to access the official PAT website hosted by the Zhejiang University Computer Science and Technology College. The primary URL for this resource is `https://www.patest.cn`. This platform serves as the central hub for all PAT-related materials, including practice problems, contest announcements, and official guidelines. Teacher Weng Kai, a prominent figure in computer science education at Zhejiang University, is intrinsically linked to the development and promotion of the PAT. Consequently, his recommended exercises and teaching resources are systematically integrated into this official ecosystem rather than being dispersed across personal or unofficial channels.

Within the PAT website, the "Practice" section is the critical entry point. Here, users will find a comprehensive problem set categorized by difficulty (Basic, Advanced, Top) and often aligned with standard curriculum progressions. To specifically target exercises that reflect Weng Kai's pedagogical approach for learning C, one should focus on the "Basic Level" problems. These are designed to reinforce fundamental C programming concepts such as control structures, arrays, functions, and basic data manipulation, which form the core of his introductory teaching. The problem descriptions typically include input/output specifications and sample cases, providing a self-contained practice environment. While the site interface is primarily in Chinese, browser translation tools can effectively bridge any language gap for international learners seeking these technical resources.

For a structured learning path mirroring a university course, one can cross-reference the PAT problem sets with the content from Weng Kai's widely used MOOC, "C Language Programming," available on platforms like China University MOOC (icourse163.org). The sequence of topics in his lectures—from variables and loops to pointers and file operations—corresponds closely to the progression of problems in the PAT Basic Level. Engaging with both resources in tandem offers a powerful combination of theoretical understanding and applied practice. It is important to note that the PAT system itself requires submitting code for real-time automated judging, which provides immediate, objective feedback on correctness, performance, and robustness, an essential mechanism for developing practical skill.

Beyond the official site, while discussions and community support may exist on forums like GitHub or programming Q&A sites, these are secondary and should be verified against the primary source. The integrity and currentness of the problem specifications are maintained solely on `patest.cn`. Therefore, for anyone aiming to master C programming through the exercises curated and advocated by Weng Kai, methodically working through the PAT Basic Level problems on the official platform constitutes the definitive, and most authentic, pathway. This approach ensures alignment with the exact standards and problem-solving philosophy emphasized in the academic context from which they originate.
