Overview of C++ Programming Language

Overview of C++

• General-purpose programming language created by Bjarne Stroustrup in 1979.
• An extension of the C programming language, supporting both procedural and object-oriented programming.
• Known for high performance and efficiency.

Key Features

• Object-Oriented Programming (OOP): Supports classes, inheritance, polymorphism, encapsulation.
• Low-level Manipulation: Can interact with hardware and memory, similar to C.
• Standard Template Library (STL): Provides ready-to-use classes and functions for data structures and algorithms (e.g., vectors, lists, queues).
• Type Safety: Strongly typed language, reducing errors and enhancing code reliability.
• Memory Management: Manual memory management with pointers, alongside automatic garbage collection in some contexts.

Basic Syntax

• Variables and Data Types:

  • Fundamental types: int, float, double, char, bool.
  • User-defined types: struct, class, enum.

• Control Structures:

  • Conditional: if, else, switch.
  • Loops: for, while, do-while.

• Functions:

  • Defined with a return type, function name, and parameters.
  • Supports function overloading.

Object-Oriented Concepts

• Classes and Objects:

  • Class: blueprint for creating objects (containers for data and functions).
  • Object: instance of a class.

• Inheritance:

  • Mechanism to create a new class based on an existing class (base and derived classes).

• Polymorphism:

  • Ability to call derived class methods through base class references or pointers.

• Encapsulation:

  • Bundling data and methods that operate on data within one unit (class).

Memory Management

• Dynamic Allocation:

  • Use of new and delete operators for allocating and deallocating memory.

• Pointers and References:

  • Pointers store memory addresses; references provide an alternative name for variables.

Common Libraries

• Standard Library: Includes input/output stream library (<iostream>), string library (<string>), and algorithm library (<algorithm>).
• Boost Libraries: A collection of portable and peer-reviewed libraries that extend the functionality of C++.

Development Tools

• Compilers: Popular ones include GCC, Clang, Microsoft Visual C++.
• Integrated Development Environments (IDEs): Examples include Visual Studio, Code::Blocks, and CLion.

Best Practices

• Use consistent naming conventions.
• Write modular code with functions and classes.
• Comment code adequately to enhance readability.
• Utilize STL for efficient data handling.
• Manage memory carefully to prevent leaks and undefined behavior.

Overview of C++

• General-purpose programming language developed by Bjarne Stroustrup in 1979
• Extension of C, combining procedural programming with object-oriented principles
• Recognized for high performance and efficiency

Key Features

• Object-Oriented Programming (OOP): Emphasizes key concepts like classes, inheritance, polymorphism, and encapsulation
• Low-level Manipulation: Provides capabilities to interface directly with hardware and memory, similar to C
• Standard Template Library (STL): Contains pre-defined classes and functions for common data structures and algorithms, enhancing development speed
• Type Safety: Strongly typed, which minimizes errors and increases reliability of code
• Memory Management: Offers manual memory management via pointers; some contexts feature automatic garbage collection

Basic Syntax

• Variables and Data Types:
  • Fundamental types include int, float, double, char, and bool
  • User-defined types can be created using struct, class, and enum
• Control Structures:
  • Conditional statements utilize if, else, and switch
  • Loop constructs include for, while, and do-while
• Functions:
  • Functions specified by return type, name, and parameters; supports function overloading

Object-Oriented Concepts

• Classes and Objects:
  • Class serves as a blueprint for objects, encapsulating data and methods
  • Object refers to an instance of a class
• Inheritance:
  • Allows creation of a new class based on an existing one, categorizing as base and derived classes
• Polymorphism:
  • Enable overriding and accessing derived class methods through base class pointers or references
• Encapsulation:
  • Combines data and methods into a single unit (class), promoting data hiding and organization

Memory Management

• Dynamic Allocation:
  • Memory allocation and deallocation are handled using new and delete operators
• Pointers and References:
  • Pointers retain memory addresses while references provide alternative names for existing variables

Common Libraries

• Standard Library: Utilizes libraries for input/output streams, string manipulation, and algorithms
• Boost Libraries: Offers a wide array of portable, peer-reviewed libraries that enhance C++ capabilities

Development Tools

• Compilers: Notable options include GCC, Clang, and Microsoft Visual C++
• Integrated Development Environments (IDEs): Examples are Visual Studio, Code::Blocks, and CLion

Best Practices

• Maintain consistent naming conventions throughout code
• Design modular code by using functions and classes
• Incorporate comments effectively for code clarity
• Leverage STL for improved efficiency in data handling
• Exercise careful memory management to avoid leaks and unintended behaviors
