C++ is a versatile programming language
that can be used to design a wide range of
software applications
Definition of C++ as a general-purpose,
high-level, compiler-based, and object-
oriented programming language It is classified as a general-purpose
language, meaning it can be used for
various purposes, unlike specialized
languages
Operating systems (e.g., DOS, Windows,
Unix)
C++ as a General-Purpose
Language Editors (e.g., Notepad, WordPad, MS Word)
Commercial applications (e.g., bank
programs, supermarket programs, hotel
programs)
Database applications (e.g., Oracle, SQL
Server, MySQL)
Examples of software that can be
developed using C++
Translators (e.g., compilers, interpreters,
assemblers)
Device drivers (e.g., printer, keyboard,
mouse)
PC and mobile games (e.g., Snake, Super
Mario, Contra)
Protocols (e.g., HTTP, FTP, telecom
protocols)
Software is a collection of programs, which
are sets of instructions
Understanding the concept of software, Software can be categorized into system
programs, and programming languages software and application software

Programming Programming Language
Language High-level languages, like C++, are closer to
human-readable language and easier to
understand
Characteristics of high-level programming They are abstracted from the underlying
languages machine-level instructions (binary code)
High-level languages require a translator
(e.g., compiler, interpreter) to convert them
into machine-readable code
Protocols define the rules and standards
for communication between different
systems or components
Importance of protocols in software
development Protocols are essential for the proper
functioning of various software
applications and systems
Advantages of C++ for Designing
Protocols C++ is particularly well-suited for designing
protocols due to its low-level control and
efficiency
Approximately 90% of telecom protocols
C++'s suitability for designing protocols are designed using C++
Examples of protocols designed with C++
include HTTP, FTP, and various other
network and communication protocols
