Identifying Non-Procedural Computer Languages
A non-procedural language, often called a declarative language, focuses on describing what the program should accomplish without specifying how to achieve it (the control flow). This contrasts with procedural languages, which detail the sequence of steps.
Language Classification
Let's analyze the given options:
- LISP: Primarily a functional programming language, emphasizing expressions and recursion. It is considered non-procedural.
- Python: A multi-paradigm language that supports procedural, object-oriented, and functional programming. However, it is predominantly used in an imperative/procedural style.
- Prolog: A classic logic programming language based on formal logic. It is inherently non-procedural.
- ML (Meta Language): A family of functional programming languages known for strong type systems and automatic memory management. It is non-procedural.
Conclusion
Among the options, LISP, Prolog, and ML are primarily categorized as non-procedural (declarative) languages. Python, while supporting functional features, is more commonly classified and used as a procedural/imperative language. Therefore, Python is the correct answer as it is NOT strictly a non-procedural language compared to the others listed.
Important Questions from Programming in C
In object-oriented programming, which keyword ensures that a member variable belongs to the class itself rather than to any specific object, thereby allowing all instances to share a single copy of that variable?
The three basic structure types used to write the algorithm for a program are sequence, selection and repetition. Which of the following is NOT an advantage of using only these structures when writing the algorithm for a program?
Which statement(s) is/are true about formation of identifier in C?
I. It consist of alphabets, digits and underscore.
II. An identifier can start with an underscore.
What is the output of the code written in C?
void main()
{
printf("%d",7%-3);
printf("%d",-7%3);
}
Which of the following statement(s) is/are true about pre-processor in C/C++?
I. To replace each #include directive with the contents of the designated file.
II. To replace each escape sequence with designated character.
III. To process macro definitions and expand macro calls.
