Sample Kerala Plus Two Computer Science (DHSE) Practice Questions

Try these sample questions to review concepts for the Kerala Plus Two Computer Science (DHSE) exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1In C++, which keyword is used to define a user-defined data type that groups related variables of possibly different types under one name?
A.namespace
B.union only
C.struct
D.typedef
Explanation: A structure (struct) groups related data members, which may have different types, under a single user-defined type name. This is a core Plus Two Computer Science topic before OOP classes.
2If s is a structure variable with member roll, which expression correctly accesses roll using the structure variable (not a pointer)?
A.s::roll
B.s.roll
C.*s.roll
D.s->roll
Explanation: The dot operator (.) accesses a member of a structure (or class) object/variable. The arrow operator (->) is used when you have a pointer to a structure.
3What does the address-of operator & return when applied to a variable in C++?
A.The value stored in the variable doubled
B.A copy of the variable on the heap
C.The size of the variable in bytes
D.The memory address of the variable
Explanation: The unary & operator yields the memory address of its operand. That address can be stored in a pointer variable of a compatible type.
4If p is a pointer to int and currently points to an array element, what does the expression *p typically evaluate to?
A.The number of elements in the array
B.The int value stored at the address held by p
C.Always zero
D.The address of p itself
Explanation: The unary * (dereference) operator accesses the object pointed to by the pointer. For an int* p, *p is the int at that address.
5Which statement best describes a nested structure in C++?
A.A structure that cannot be passed to functions
B.A structure that contains another structure as a member
C.A structure allocated only on the heap
D.A structure that can only hold int members
Explanation: Nested structures contain a member whose type is itself a structure, allowing hierarchical grouping of related data (for example, Date inside Employee).
6If ptr is a pointer to a structure variable, which syntax correctly accesses member name of that structure?
A.ptr.name
B.ptr::name
C.ptr->name
D.*ptr->name only when name is a pointer
Explanation: When you have a pointer to a structure, use the arrow operator: ptr->name is equivalent to (*ptr).name.
7An array of structures is useful primarily because it allows:
A.Only one structure variable in the entire program
B.Storing multiple records of the same structure type in contiguous indexed form
C.Automatic sorting of structure members by type
D.Conversion of all members to the same data type
Explanation: An array of structures holds many instances of the same structure type (for example, student[50]), each accessible by index — ideal for tables of records.
8Consider: int a = 10; int *p = &a; *p = 25; What is the value of a after these statements execute?
A.10
B.Address of a
C.25
D.Undefined
Explanation: p points to a. Assigning *p = 25 writes 25 into the memory location of a, so a becomes 25. This is a classic pointer side-effect / code-output item.
9In object-oriented programming, an object is best described as:
A.A compiler directive
B.A synonym for a source file
C.Only a collection of global functions
D.An instance of a class
Explanation: A class is a blueprint; an object is a concrete instance created from that class, with its own state (data) and behavior (functions/methods).
10Which OOP principle hides internal data and exposes a controlled interface?
A.Pipelining
B.Pagination
C.Encapsulation
D.Fragmentation
Explanation: Encapsulation bundles data with the functions that operate on it and typically restricts direct external access (for example, private members with public methods).

About the Kerala Plus Two Computer Science (DHSE) Exam

Kerala Plus Two Computer Science is the Class 12 Higher Secondary public examination computer science paper under the Directorate of Higher Secondary Education (DHSE), Directorate of General Education, Government of Kerala. It is distinct from Computer Applications (typically offered in Commerce/Humanities combinations). It assesses SCERT Kerala Higher Secondary Computer Science themes: structures and pointers; object-oriented programming; data structures and operations; web technology; HTML web designing; client-side JavaScript; web hosting; database management systems; SQL; server-side PHP; advances in computing; and ICT and society, with foundational boolean algebra, networks, file handling, and computational thinking from the Plus One–Plus Two continuum. The official assessment is TE + CE + Practical Evaluation for a subject total of 100 marks (theory commonly about 2 hours plus cool-off). Fees and exact blueprints are notified by DHSE (beta.hseportal.kerala.gov.in; dhse.kerala.gov.in). Pass marks are commonly described near ~30% aggregate with separate TE minima as notified. The 100 questions on this page are a free English-language multiple-choice study adaptation with full explanations, code-output reasoning, and boolean/numerical items; they are not a full simulation of the official mixed theory paper, practical lab, or CE evidence.

Exam sponsor: Directorate of Higher Secondary Education (DHSE), Kerala. The requirements and fees below concern the certification or admission exam, separate from our free practice resources.

Kerala Plus Two Computer Science (DHSE): Suggested Study Strategy

1Practice official DHSE/SCERT Computer Science model papers under timed ~2 h conditions so you can switch from MCQ drills to written programs, algorithm traces, and SQL answers.
2For data-structure items, draw stack/queue states after each operation and note overflow/underflow — boards often award stepwise marks.
3Memorize LIFO vs FIFO, primary vs foreign keys, HTTP vs HTTPS, client-side vs server-side roles, and SQL clause order (SELECT–FROM–WHERE–GROUP BY–HAVING–ORDER BY).
4Trace short C++/JavaScript/PHP snippets on paper before looking at options; code-output questions are high-yield for Computer Science.
5Do not neglect practicals and CE: lab programs, SQL practice, web pages, and viva concepts contribute significantly to the subject total.
6Remember Computer Science ≠ Computer Applications — use the correct SCERT textbook and combination for your stream.
7Use English/Malayalam textbooks as directed by your school; this free bank is an English MCQ adaptation only.
