About this previous year paper
This is the complete B.Tech 1st Semester Programming for Problem Solving (C Language) question paper designed as per the latest 100-mark university exam structure. The paper is fully aligned with the syllabus and tests the student’s knowledge of C programming concepts, algorithms, operators, functions, loops, arrays, pointers, strings, structures, file handling, and computer fundamentals.
The paper is divided into Section A, Section B, Section C, covering short-answer, medium-answer, and long-answer analytical questions.
This question paper is highly valuable for AKTU B.Tech 1st-year students, helping them prepare efficiently for university exams and viva.
SECTION A – Short Answer Questions (10 × 2 = 20 Marks)
This section examines fundamental concepts of C programming and computer basics:
Compiler vs Interpreter
Characteristics of a good algorithm
Scope & lifetime of variables
Recursive function to calculate factorial
How break statement works
Precedence & associativity in expressions
Syntax vs logical errors
Arrays vs linked lists
Linked list structure (self-referential structs)
Difference between structure & union
Memory hierarchy of a computer
These questions help strengthen conceptual clarity and fundamentals.
SECTION B – Descriptive Questions (Attempt Any 3 × 10 = 30 Marks)
Searching Algorithms
Linear search & binary search
Time complexity (O(n), O(log n))
C Program – Steel Grade System
Based on hardness, carbon content & tensile strength
→ Outputs grade from 5 to 10.
Call by Value vs Call by Reference
Algorithm + C program to swap two numbers using reference
Understanding of parameter passing
Selection Sort
Explanation
Algorithm
Sorting given list: 26, 54, 93, 17, 77, 31, 44, 55, 20
Preprocessor Directives
Macro Expansion
File Inclusion
These help students master coding logic & algorithm writing.
SECTION C – Long Questions (5 × 10 = 50 Marks)
Q3 – Computer Fundamentals / Data Types
Choose one:
Components of computer with block diagram + OS definition
OR
Data types in C, memory, format specifier & range
Q4 – Operators / Control Structures
Choose one:
Arithmetic operators with examples + precedence & associativity
OR
Switch case control structure + role of break statement
Q5 – Loops / Functions
Choose one:
Syntax of while, do-while, for + C program to multiply a 4×4 matrix
OR
Definition of function + how values pass between calling & called function
Q6 – ENUM, Strings & Time Complexity
Choose one:
Short notes on enumerated data type & string
OR
Order of complexity (Big-O notation) and various time complexities
Q7 – Dynamic Memory / Command-line Arguments
Choose one:
Dynamic Memory Allocation: malloc(), calloc(), realloc(), free() + lifetime of dynamically created variables
OR
Command-line arguments in C with example
These questions cover the most important high-weightage topics asked in AKTU examinations.
