About this previous year paper
This question paper assesses a student's understanding of C programming concepts, algorithms, file handling, data types, operators, control statements, OS basics, ALU, and pointer usage.
It is divided into three sections, covering definitions, programs, comparisons, and applied problem-solving.
SECTION – A (10 × 2 = 20 Marks)
This section contains ten short-answer questions, requiring brief definitions or outputs.
Topics include:
Pointers and initialization
Role of ALU
Difference between <stdio.h> and "stdio.h"
Functions of operating system
Escape sequence characters
Enumerated data type
Output prediction of a left-shift operator
Behavior of an infinite loop
Structured programming
Modulus operation with negative numbers
This section checks basic C language syntax, OS fundamentals, and simple computational logic.
SECTION – B (5 × 10 = 50 Marks)
Students must attempt any five medium-length programming or descriptive questions.
Topics include:
C program to reverse a string using pointers
Formatted vs unformatted I/O functions
Fibonacci series using recursion
Flowchart + algorithm for sum & average
Static vs extern variables (with example)
Switch-case vs nested if (with examples)
Prime number checking program
Difference between structure & union, and employee record program using structure
This section evaluates algorithmic thinking, programming logic, code writing skills, and conceptual understanding.
SECTION – C (2 × 15 = 30 Marks)
Students must attempt any two long-answer questions.
Topics include:
Control Statements & Type Concepts
Break vs continue (examples)
Type conversion vs type casting
File Handling & Operators
File operations in C and program to count characters in a file
Types of operators; precedence vs associativity
Matrices & C Concepts
Program for multiplication of two M × N matrices
Explanation of:
Preprocessor
Double precision
Array of structures
This section tests in-depth programming, file handling, operator hierarchy, and structured data concepts.
