(SEM-I) THEORY EXAMINATION 2019-20 PROGRAMMING FOR PROBLEM SOLVING

This is the complete B.Tech 1st Semester Programming for Problem Solving (KCS101) question paper designed as per the official 100-mark university exam pattern. The paper includes C programming fundamentals, algorithms, flowcharts, operators, control statements, functions, arrays, pointers, structures, file handling, and complete programming logic-building skills.

This question paper is extremely useful for students who want to practice C programs, understand theory concepts, revise important definitions, and prepare for university exams and lab vivas.

SECTION A – Short Answer Questions (10 × 2 = 20 marks)

This section checks basic understanding of C programming fundamentals:

Storage classes with examples

Functionalities of operating system

Implicit vs explicit type conversion

Mixed operands with examples

Function prototype

Difference between while and do-while loop

Algorithm for second-largest number in array

Structure vs union

Role of C preprocessor

Pointer arithmetic

These questions help revise core concepts essential for coding logic.

SECTION B – Medium-Length Questions (Attempt Any 3 × 10 = 30 marks)

This part includes conceptual explanations and practical programs:

Major components of a digital computer with block diagram

Operators in C, precedence, and associativity with examples

Program to check palindrome number

Program + flowchart for real roots of quadratic equation

Macro definitions with arguments (simple interest & amount) using header file "interest.h"

This section strengthens programming logic and theoretical clarity.

SECTION C – Long Answer Questions (5 × 10 = 50 marks)

Each question has two alternatives. Students must attempt one from each.

Q3 – Compilation & C Program Structure

Difference between compiler & interpreter, linker & loader, break & continue
OR

Data types in C with memory size, format specifier, range + structure of a C program

Q4 – Conditional Statements & Decision Making

Different conditional statements in C (if, nested if, switch, conditional operator)
OR

Flowchart + program to identify triangle type (isosceles, equilateral, scalene, right-angled)

Q5 – Loops, Functions & Patterns

Program to generate Fibonacci series <100, sum & count + pattern printing
OR

Call by value vs call by reference + circle area & circumference using call by reference

Q6 – Arrays & Structures

Sorting meaning + bubble sort program + flowchart
OR

Structure for employee record + program to input 100 employees & display those earning >₹20,000

Q7 – File Handling & Dynamic Memory

File modes + program to separate odd & even numbers from INPUT file to ODD & EVEN files
OR

Features of pointers + dynamic memory allocation example (malloc, calloc, free)

These questions test long programming skills, conceptual depth, and C language proficiency.
