Theory Examination (Semester-II) 2015-16 COMPUTER SYSTEM & PROGRAMMING IN C

This question paper evaluates students’ understanding of C programming, algorithms, operating system basics, memory concepts, program execution, file handling, and UNIX architecture.
It is divided into three sections covering brief answers, descriptive questions, and applied programming tasks.

SECTION – A (10 × 2 = 20 Marks)

This section contains ten short questions requiring brief, precise answers.
Topics include:

Layout/structure of a C program

Definition of an algorithm

Components of an operating system

Conversion of octal to hexadecimal

Android operating system (overview)

UNIX architecture

RAM vs ROM

Meaning of software

Structured programming

Storage classes in C

This section tests basic theory, fundamental C concepts, and OS knowledge.

SECTION – B (5 × 10 = 50 Marks)

Students must attempt any five medium-length conceptual or programming questions.
Topics include:

Special features of void pointers

Parameter passing mechanisms (call by value/reference)

C program to print a character pattern

Disadvantages of if-else-if ladder

Principles of recursion

Relationship between structures and pointers

Enumerated data types with explanation

This section measures conceptual clarity, coding ability, and logical understanding.

SECTION – C (2 × 15 = 30 Marks)

Students must attempt any two long-answer questions.

Topics include:

Preprocessor Directives

What they are

Explanation of three directives (e.g., #include, #define, #ifdef)

Program Execution

Loading and linking process explained

C program to reverse digits of a number

File Handling & Sorting

C program to read student records (name & age)

Sorting records by name

Displaying sorted output

This section assesses in-depth programming, OS-level understanding, and applied file operations.
