NYI NYI MOE HTET COMP 333 ASSIGNMENT 2 1. Why were linguists interested in artificial intelligence in the late 1950s? They were concerned with natural language processing. 2. What dialect of Lisp is used for introductory programming courses at some universities? Common Lisp and Scheme dialects. 3. What are two characteristics of C that make it less safe than Pascal? C allows the use of pointers and direct manipulate memory addresses, but this can lead to memory leaks if not handled properly. C has poor type checking which can result in various complications and security vulnerabilities. In contrast, Pascal does not allow the use of pointers, providing a safer approach to memory management, and it has stricter type checking. 4. What is a nonprocedural language? A nonprocedural language is a language where programmers specify what needs to be accomplished without detailing the step-by-step execution details, and leave the language to handle the underlying execution. 5. Why does C++ include the features of C that are known to be unsafe? C++ includes potentially unsafe features of C to maintain backward compatibility, facilitating the transition for C programmers to embrace object-oriented programming. Additionally, it offers high performance by retaining low-level capabilities such as direct memory access and pointers. Moreover, many existing codebases, libraries, and APIs are written in C. By including C features, C++ makes it easier to integrate and use these resources. 6. What is the relationship between JavaScript and PHP, in terms of their use? Both JavaScript and PHP are languages mainly used in web development to create dynamic and interaction web applications. JavaScript runs on the clients’ browser, handling user interactions and retrieval of data from backend servers. PHP is executed on web servers to manage server-side functionalities such as database operations and generation of dynamic content. 7. Where are servlets executed? They are executed on a Web server system.
