Study Notes
Intermediated Programming with C++
Key Concepts
- Understand the principles of intermediated programming with C++
- Demonstrate understanding of various concepts, including:
Structures and Classes
- Structures (struct) and classes are user-defined data types
- Key differences between structures and classes:
- Structures have public access by default, while classes have private access
- Inheritance in classes is private by default, whereas in structures it is public
Polymorphism in C++
- Polymorphism: ability of an object to take multiple forms
- Types of polymorphism in C++:
- Compile-time polymorphism (function overloading, operator overloading)
- Run-time polymorphism (function overriding)
Templates
- Templates: a feature in C++ that allows functions and classes to operate with generic data types
- Advantages of templates:
- Code reusability
- Increased efficiency
Namespaces
- Namespaces: a way to group named entities, such as functions, variables, and classes
- Purpose of namespaces:
- Avoid naming conflicts
- Organize code
STL (Standard Template Library)
Vector
- Vector: a sequence container that stores elements dynamically
- Key features of vectors:
- Dynamic memory allocation
- Automatic resizing
Stacks
- Stack: a linear data structure that follows LIFO (Last In, First Out) principle
- Stack operations:
- Push (add element)
- Pop (remove element)
- Top (access top element)
Map
- Map: an associative container that stores key-value pairs
- Key features of maps:
- Fast look-up, insertion, and deletion
- Ordered or unordered maps
Algorithms in C++
- Algorithms: a set of instructions to solve a specific problem
- Types of algorithms in C++:
- Sorting algorithms (e.g., bubble sort, quick sort)
- Searching algorithms (e.g., linear search, binary search)
Mini Database in C++
- A simple database application using C++
- Key features:
- Data storage and retrieval
- Basic CRUD (Create, Read, Update, Delete) operations
Intermediated Programming with C++ Principles
- Demonstrate an understanding of structures and classes in C++:
- Define a blueprint for creating objects
- Classes: user-defined data types that encapsulate data and functions
- Structures: similar to classes, but members are public by default
Polymorphism in C++
- Understand polymorphism in C++:
- Ability of an object to take on multiple forms
- Achieved through function overloading and operator overloading
- Allows for more flexibility and generic code
Templates
- Learn about templates in C++:
- Generic programming: reuse code with different data types
- Templates: parameterized types that allow for type safety
- Function templates and class templates
Namespaces
- Understand namespaces in C++:
- Organize and separate global identifiers into distinct namespaces
- Avoid naming conflicts and improve code readability
- Use the
usingdirective to access namespace members
Standard Template Library (STL)
- Familiarize with key STL components:
- Vector: dynamic array with automatic memory management
- Stack: last-in, first-out (LIFO) data structure
- Map: associative container that stores key-value pairs
- Algorithms: reusable functions for common tasks
C++ STL Container and Algorithms
-
Learn about the following STL containers:
- Vector: dynamic array with automatic memory management
- Stack: last-in, first-out (LIFO) data structure
- Map: associative container that stores key-value pairs
-
Understand the importance of algorithms in C++:
- Reusable functions for common tasks
- Sorting, searching, and manipulating data
Mini Database in C++
- Understand how to create a mini database in C++:
- Use STL containers to store and manage data
- Implement basic CRUD (Create, Read, Update, Delete) operations
- Demonstrate basic data storage and retrieval capabilities
