Explain the key feature that distinguishes structured programming from object-oriented programming.
Why is Python considered a scripting language rather than a traditional programming language?
What challenges do programmers face when using low-level languages compared to high-level languages?
Answers and Descriptions
Answer: Machine language consists of binary code (0s and 1s) directly executable by the CPU, while assembly language uses mnemonic codes (e.g., ADD, MOV) that are more human-readable but require translation into machine code.
Description: Machine language is hardware-specific and difficult to write, while assembly language provides a slightly abstracted layer, using mnemonics to represent machine instructions, making it easier to program but still low-level.Answer: Procedural languages focus on step-by-step instructions to achieve a task (e.g., C), while declarative languages specify the desired outcome without detailing the steps (e.g., SQL).
Description: Procedural languages emphasize control flow and explicit procedures, suitable for general-purpose programming. Declarative languages are used in domains like databases, where the system determines how to achieve the result, simplifying certain tasks.Answer: Structured programming organizes code into modular blocks (e.g., loops, conditionals) to improve clarity, while object-oriented programming uses objects and classes to encapsulate data and behavior.
Description: Structured programming, as in Pascal, avoids unstructured jumps (e.g., GOTO), enhancing readability. Object-oriented programming, as in Java, builds on this by introducing inheritance and polymorphism, ideal for complex systems.Answer: Python is considered a scripting language because it is often used for automating tasks, rapid prototyping, and executing scripts without requiring compilation, though it can also function as a general-purpose programming language.
Description: Scripting languages prioritize ease of use and flexibility, often interpreted at runtime (e.g., Python scripts for web automation). Traditional programming languages like C++ typically involve compilation and are used for system-level development.Answer: Low-level languages require detailed hardware knowledge, are error-prone, and are harder to debug, while high-level languages are more abstract, user-friendly, and portable across platforms.
Description: Programming in machine or assembly language involves managing registers and memory directly, increasing complexity. High-level languages abstract these details, allowing focus on logic and functionality, but may sacrifice fine-grained control.
