About this previous year paper
This document contains the complete Theory Examination Question Paper for Computer Programming (C Programming).
The paper is designed for B.Tech / Diploma / Computer Science students, with a total of 100 marks and duration of 3 hours.
It evaluates a student's understanding of C programming fundamentals, data structures, control structures, functions, arrays, pointers, files, and basic computer architecture.
Structure of the Question Paper
The question paper is divided into three major sections: Section A, Section B, and Section C, each focusing on different levels of understanding—from short answers to long descriptive programming-based questions.
SECTION – A (10 × 2 = 20 Marks)
This section contains ten very short questions, each carrying 2 marks.
These questions test the student's knowledge of basic C concepts, definitions, and short logic-based tasks.
Topics include:
Modular programming approach
Operators in C
Structured programming
Type conversion
Simple function writing (swap without third variable)
Function declaration
File opening modes
Linked list meaning
Use of switch statement
Basic data types in C
This section focuses on concept clarity and the student must answer briefly and precisely.
SECTION – B (5 × 10 = 50 Marks)
Students must attempt any five questions.
Each question is descriptive and involves theoretical explanation or C programming logic.
The topics covered:
(a) Digital computer & block diagram
Testing understanding of input, output, memory, CPU, ALU, CU, etc.
(b) Program for sum of digits
Checking logic-building and loop usage.
(c) Array reverse-copy program
Tests understanding of arrays and indexing.
(d) Operating System – Definition, types & functions
Checking OS fundamentals such as process management, memory management, I/O control, etc.
(e) Matrix multiplication program
Tests nested loops and multi-dimensional arrays.
(f) Sorting program (ascending order)
Evaluates ability to use sorting logic such as bubble sort/selection sort.
(g) String concept, functions & user-defined strcmp
Focuses on string handling and custom comparison logic.
(h) Pointer concepts & dynamic memory allocation
Tests concepts of pointer variables, malloc, calloc, realloc, free, etc.
This section checks a student’s programming ability, problem-solving approach, and clarity of core concepts.
SECTION – C (2 × 15 = 30 Marks)
Students must attempt any TWO questions.
These are long answer questions, requiring detailed explanation, syntax, and C programs.
Question 3:
Define structure with syntax and write a C program to compare two dates (dd/mm/yyyy).
If equal → print “Equal”
Otherwise → print “Unequal”
This tests conceptual and practical understanding of structures, user-defined data types, and conditional logic.
Question 4: (Any TWO short notes)
Stack – push and pop operations
Linked list (types, node structure, applications)
Command line arguments in C
This checks knowledge of data structures and basic program execution concepts.
Question 5:
File opening modes (r, w, a, r+, w+, a+, etc.)
PLUS
A C program to read student records (name + age) from a file and display them sorted by name.
This tests:
File handling
Structures
File input/output operations
Sorting techniques
