Just go through below points i hope u will clear your queries almost..!!
UNIT 1: PROGRAMMING IN C++
REVIEW: C++ covered In Class -XI,
Defining a symbol name using typedef keyword and defining a macro using
#define directive;
Need for User defined data type;
Structures:
Defining a Structure, Declaring structure variables, Accessing structure elements,
Passing structure to Functions as value and reference argument/parameter,
Function returning structure, Array of structures, passing an array of structure as
an argument/ a parameter to a function;
Object Oriented Programming:
Concept of Object Oriented Programming – Data hiding, Data encapsulation,
Class and Object, Abstract class and Concrete class, Polymorphism
(Implementation of polymorphism using Function overloading as an example in
C++); Inheritance, Advantages of Object Oriented Programming over earlier
programming methodologies,
Implementation of Object Oriented Programming concepts in C++:
Definition of a class, Members of a class - Data Members and Member Functions
(methods), Using Private and Public visibility modes, default visibility mode
(private); Member function definition: inside class definition and outside class
definition using scope resolution operator (::); Declaration of objects as instances
of a class; accessing members from object(s), Array of type class, Objects as
function arguments - pass by value and pass by reference;
Constructor and Destructor:
Constructor: Special Characteristics, Declaration and Definition of a constructor,
Default Constructor, Overloaded Constructors, Copy Constructor, Constructor
with default arguments;
Destructor: Special Characteristics, Declaration and definition of destructor;
 

 

Inheritance (Extending Classes): Concept of Inheritance, Base Class, Derived
Class, Defining derived classes, protected visibility mode; Single level
inheritance, Multilevel inheritance and Multiple inheritance, Privately derived,
Publicly derived and Protectedly derived class, accessibility of members from
objects and within derived class(es);
Data File Handling:
Need for a data file, Types of data files – Text file and Binary file;
Basic file operations on text file: Creating/Writing text into file, Reading and
Manipulation of text from an already existing text File (accessing sequentially);
Binary File: Creation of file, Writing data into file, Searching for required data
from file, Appending data to a file, Insertion of data in sorted file, Deletion of data
from file, Modification of data in a file;
Implementation of above mentioned data file handling in C++;
Components of C++ to be used with file handling:
Header file: fstream.h; ifstream, ofstream, fstream classes;
Opening a text file in in, out, and app modes;
Using cascading operators for writing text to the file and reading text from the file;
open(), get(), put(), getline() and close() functions; Detecting end-of-file (with or
without using eof() function);
Opening a binary file using in, out, and app modes;
open(), read(), write() and close() functions; Detecting end-of-file
without using eof() function); tellg(), tellp(), seekg(), seekp() functions
(with or
Pointers:
Declaration
and
Initialization
of
Pointers;
Dynamic
memory
allocation/deallocation operators: new, delete; Pointers and Arrays: Array of
Pointers, Pointer to an array (1 dimensional array), Function returning a pointer,
Reference variables and use of alias; Function call by reference. Pointer to
structures: Deference operator: *, ->; self referencial structures;
 

Arrays:
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, Bubble sort), concatenation of two linear arrays, merging of two sorted
arrays;
 

 

Database Concepts:
Relational data model: Concept of domain, tuple, relation, key, primary key,
alternate key, candidate key;
Relational algebra: Selection, Projection, Union and Cartesian product;
Structured Query Language:
General Concepts: Advantages of using SQL, Data Definition Language and
Data Manipulation Language;
Data types: NUMBER, CHARACTER, DATE;
SQL commands:
CREATE TABLE, DROP TABLE, ALTER TABLE, UPDATE...SET..., INSERT,
DELETE;
SELECT, DISTINCT, FROM, WHERE, IN, BETWEEN, GROUP BY, HAVING,
ORDER BY;
SQL functions: SUM, AVG, COUNT, MAX and MIN;
Note: Implementation of the above mentioned commands could be done on any
SQL supported software.
 

 

Evolution of Boolean algebra, Binary-valued Quantities, Boolean Variable,
Boolean Constant and Boolean Operators: AND, OR, NOT; Truth Tables;
Closure Property, Commutative Law, Associative Law, Identity law, Inverse law,
Principle of Duality, Idempotent Law, Distributive Law, Absorption Law, Involution
law, DeMorgan's Law and their applications;
