Study Notes

C++ Overview

  • C++ is a general-purpose, high-level, compiler-based, and object-oriented programming language.

General Purpose Nature of C++

  • Purpose refers to the uses of C++.
  • "General" implies variety, like items in a general store.
  • C++ is a multi-purpose language able to design different types of software.

Software Designed with C++

  • Operating Systems: DOS, Windows, Unix are examples.
  • Editors: Notepad, WordPad, MS Office Word, DOS Edit, and Edit Plus are examples.
  • Commercial Applications: Used in billing programs for shops, bank transactions, and programs for colleges and hotels.
  • Database Software: Oracle, SQL Server, and MySQL are examples; Oracle is mainly designed using C and C++.
  • Translators: Converts source code to object code.
  • Compilers and Interpreters: Converts high-level languages to machine code.
  • Assemblers: Converts low-level languages to machine code.
  • C++ employs a compiler as its translator, classifying it as a compiler-based programming language.
  • Device Drivers: Enables interaction with hardware like printers, keyboards, and mice.
  • C and C++ are used to create device drivers.
  • PC and Mobile Games: Snake on Nokia, Mario, Super Mario, and Contra are examples.
  • Protocols: C++ is used for designing protocols; 90% of telecom protocols are designed in C++.
  • HTTP and FTP are examples of protocols designed with C++.

High-Level Programming Language

  • Software is a collection of programs.
  • Programs are instruction sets.
  • Software is a digitalized automated process.

Software as a Digitalized Automated Process

  • A media player exemplifies software as a collection of programs controlling buttons and functions.
  • Digitalized: Displaying elapsed time in a media player shows digital representation.
  • Automated: Rewind or repeat buttons automate playback.

Types of Software

  • System Software: Essential for computer operation.
  • Application Software: Designed for specific tasks.
  • Analogy: The heart is system software, organs are application software in the body.
  • System Software Examples: Operating systems (Windows, Unix, Linux), device drivers, and translators.
  • Application Software Examples: Tally, Oracle, VLC media player, Photoshop, WhatsApp, and Facebook.
  • Application software depends on system software and a working operating system.
  • Each application is designed for a specific operation.
  • Tally is for accounting, Oracle for databases, VLC for media, and Photoshop for photo management.
