open(), read(), write() and close() functions; Detecting end-of-file  (with or  without using eof()

function); tellg(), tellp(), seekg(), seekp() functions.

reference. Pointer to structures: De-reference/Deference operator: *, ->; self referencial structures;


Introduction to data structure, primitive and non-primitive data structure, linear and non-linear structure,

static and dynamic data structure.


One and two Dimensional arrays: Sequential allocation and address calculation;

One dimensional array: Traversal, Searching (Linear, Binary Search), Insertion of an element in an

array, deletion of an element from an array, Sorting (Insertion, Selection)

Two-dimensional arrays: Traversal, Finding sum/difference of two NxM arrays containing numeric

values, Interchanging Row and Column elements in a two dimensional array;

Stack (Array and Linked implementation of Stack):

Introduction to stock (LIFO _ Last in First Out Operations)

INFIX to POSTFIX notation and evaluation of Postfix expression;

Queue: (Circular Array and Linked Implementation):

Introduction to Queue (FIFO - First in First out operations)

Operations on Queue (Insert and Delete) and its Implementation in C++.161


Database Concepts: Introduction to data base concepts and its need.

Relational data model: Concept of domain, tuple, relation, key, primary key, alternate key, candidate


Relational algebra: Selection, Projection, Union and Cartesian product;

Structured Query Language:

General Concepts: Advantages of using SQL, Data Definition Language and Data Manipulation



SQL commands:



SQL functions: SUM, AVG, COUNT, MAX and MIN;

Obtaining results (SELECT query) from 2 tables using equi-join, Cartesian Product and Union

Note: Implementation of the above mentioned commands could be done on any SQL supported

software on one or two tables.


Role of Logical Operations in Computing.

Binary-valued Quantities, Logical Variable, Logical Constant and Logical Operators: AND, OR, NOT;

Truth Tables; Closure Property, Commutative Law, Associative Law, Identity law, Inverse law, Principle

of Duality, Idem potent Law, Distributive Law, Absorption Law, Involution law, DeMorgan's Law and

their applications;

Obtaining Sum of Product (SOP) and Product of Sum (POS) form from the Truth Table, Reducing

Boolean Expression (SOP and POS) to its minimal form, Use of Karnaugh Map for minimization of

Boolean expressions (up to 4 variables);

Application of Computing Logic:

Building up logic circuits using basic Logic Gates (NOT, AND, OR, NAND, NOT)

Use of Boolean operators (NOT, AND, OR) in SQL SELECT statements

Use of Boolean operators (AND, OR) in search engine queries.162
