(SEM II) THEORY EXAMINATION 2022-23 PROGRAMMING FOR PROBLEM SOLVING

The Programming in C / Computer Concepts Question Paper (2022–23) is structured to assess a student's conceptual understanding of programming fundamentals, algorithmic logic, C language syntax, program execution flow, data structures, storage classes, file handling, and computational problem-solving abilities. The exam carries 70 marks and allows students to answer in Hindi, English, or a mixed language, making it convenient for learners of different linguistic backgrounds.

The paper begins with Section A, a set of short-answer questions designed to test foundational concepts. Students respond to definitions and comparisons such as the difference between an algorithm and a program, functions of an operating system, comparison of linear vs. binary search, differences between structure and union, meaning of pointer arithmetic, and a brief explanation of linked lists. One question also requires predicting the output of a C program, testing students’ logical reasoning and understanding of control flow.

Section B focuses on descriptive and practical programming-based questions. Students may be asked to explain flowcharts along with their advantages, define recursion and write a recursive function for factorial, reverse a number using C code, discuss key string functions with code snippets, or explain the usage of fopen() with file modes in C. This section evaluates the student’s ability to apply theoretical concepts into working programs and to demonstrate clarity in coding logic.

Section C includes long, technical questions requiring deeper understanding and detailed programming. Students may discuss storage classes (auto, static, extern, register) along with scope, lifetime, and default values, or elaborate on primitive data types with memory sizes and format specifiers. Additional questions involve writing programs for printing grade categories based on marks, explaining bitwise operators and evaluating expressions, differentiating between while and do-while loops with pattern printing programs, performing matrix multiplication using arrays, explaining call by value vs call by reference, writing selection sort, and demonstrating static vs dynamic memory allocation. The section concludes with file handling tasks such as writing content to a file and reading it back using C file handling functions.

Overall, this question paper is designed to develop logical thinking, structured coding, understanding of C programming constructs, and confidence in writing and analyzing programs. It ensures students gain a strong foundation that prepares them for advanced programming and computer science subjects.

Sample Questions from the Question Paper
