member functions, inline function, friend functions, static members, and references.
Inheritance: Class hierarchy, derived classes, single inheritance, multiple, multilevel, hybrid
inheritance, role of virtual base class, constructor and destructor execution, base
initialization using derived class constructors.
Polymorphism: Binding, Static binding, Dynamic binding, Static polymorphism: Function
Overloading, Ambiguity in function overloading, Dynamic polymorphism: Base class
pointer, object slicing, late binding, method overriding with virtual functions, pure virtual
functions, abstract classes.
Operator Overloading: This pointer, applications of this pointer, Operator function, member
and non member operator function, operator overloading, I/O operators. Exception
handling: Try, throw, and catch, exceptions and derived classes, function exception
declaration, unexpected exceptions, exception when handling exceptions, resource
capture and release.

Introduction:
Programmers write instructions in various programming languages to perform their computation tasks
such as:
(i) Machine level Language
3 P.T.O
, (ii) Assembly level Language
(iii) High level Language
Machine level Language :
Machine code or machine language is a set of instructions executed directly by a computer's central
processing unit (CPU). Each instruction performs a very specific task, such as a load, a jump, or an
ALU operation on a unit of data in a CPU register or memory. Every program directly executed by a
CPU is made up of a series of such instructions.
Assembly level Language :
An assembly language (or assembler language) is a low-level programming language for a computer,
or other programmable device, in which there is a very strong (generally one-to-one) correspondence
between the language and the architecture's machine code instructions. Assembly language is
converted into executable machine code by a utility program referred to as an assembler; the
conversion process is referred to as assembly, or assembling the code.
High level Language :
High-level language is any programming language that enables development of a program in much
simpler programming context and is generally independent of the computer's hardware architecture.
High-level language has a higher level of abstraction from the computer, and focuses more on the
programming logic rather than the underlying hardware components such as memory addressing and
register utilization.
The first high-level programming languages were designed in the 1950s. Now there are dozens of
different languages, including Ada , Algol, BASIC, COBOL, C, C++, JAVA, FORTRAN, LISP,
Pascal, and Prolog. Such languages are considered high-level because they are closer to human
languages and farther from machine languages. In contrast, assembly languages are considered
lowlevel because they are very close to machine languages.
The high-level programming languages are broadly categorized in to two categories:
(iv) Procedure oriented programming(POP) language.
(v) Object oriented programming(OOP) language.
• Procedure Oriented Programming Language
In the procedure oriented approach, the problem is viewed as sequence of things to be done such as
reading , calculation and printing.
