(SEM 1) THEORY EXAMINATION 2017-18 COMPUTER SYSTEM & PROGRAMMING IN C

This is a complete C Programming (Problem Solving Using C) question paper prepared according to a 70-mark university examination pattern. The paper covers the full syllabus of C language fundamentals, algorithms, data types, functions, recursion, loops, arrays, pointers, structures, file handling, macros, and operating systems.

The paper is divided into three structured sections – A, B, and C, containing short concept-based questions, medium descriptive questions, and long programming/problem-solving questions.

It is extremely useful for B.Tech, BCA, Diploma, and IT foundation students, especially those preparing for semester exams, viva, practicals, and internal assessments.

SECTION A – Short Questions (7 × 2 = 14 Marks)

This section tests fundamental concepts of C programming:

Actual vs formal arguments (with example)

Function declaration vs function definition

Flowchart to find greatest among three numbers

Function to swap two values without third variable

Difference between compiler and interpreter

Why do-while loop is used (properties)

Macro evaluation problem using #define

These questions check the student's conceptual clarity and understanding of C basics.

SECTION B – Descriptive Questions (Attempt Any 3 × 7 = 21 Marks)

Operating System Basics

Types and functions of OS: memory management, process scheduling, file handling, I/O control

Data Types in C

Integer, float, char, double

Derived types: array, pointer, structure, union

Size, range, and examples

Series Program Using For Loop

Add first 7 terms of:

• 11!+22!+33!+…\frac{1}{1!} + \frac{2}{2!} + \frac{3}{3!} + \dots1!1​+2!2​+3!3​+…

Pointers & Dynamic Memory Allocation

Definition of pointer

malloc(), calloc(), realloc(), free() with examples

Bubble Sort Program

Sorting integers in ascending order

This section focuses on writing C programs and applying theoretical concepts.

SECTION C – Long Questions (7 Marks Each)

Q3 – Basic Programming (Palindrome / Prime)

Choose one:

Program to check whether a number is a palindrome
OR

Program to check whether a number is prime

Q4 – Recursion / Parameter Passing

Choose one:

Recursion + Fibonacci series program
OR

Difference between call by value and call by reference (which is more efficient & why)

Q5 – Matrices / Structures

Choose one:

Program to multiply two matrices (dynamic input)
OR

Structure definition + program to compare two dates using a structure

Q6 – Files / Macros

Choose one:

File opening modes + Program to copy content of one file to another
OR

What is a macro? How substitution works?

Macro as variable vs macro as function (examples)

Q7 – Digital Computer / (Missing second option)

Choose one:

Definition of digital computer

Block diagram + explanation of CPU, memory, I/O devices, storage units
(Second option in the question is incomplete)

Why This Question Paper Is Very Useful for Students

Follows latest university exam format (70 marks)

Covers full C programming syllabus

Mix of theory + algorithms + coding questions

Includes repeated and high-weightage topics

Ideal for revision, self-study, internal exams, and viva preparation

Strengthens problem-solving and logic-building abilities

This paper is extremely helpful for students of CSE, IT, AI-ML, BCA, MCA, Diploma (CS), and Polytechnic.
