Basics

Introduction

C++ is a powerful language for systems and web with high performance.

Installation

C++ installation uses compilers like GCC or MSVC for development.

Running Code

C++ code runs via g++ or Visual Studio with .cpp files.

Syntax

C++ syntax uses semicolons and curly braces with strong typing.

Variables

C++ variables use explicit types with const for immutability.

Data Types

C++ data types include int string and bool with templates.

Type Conversion

C++ type conversion uses static_cast for safe type changes.

Operators

C++ operators include arithmetic and bitwise with precedence.

If Else

C++ if-else statements control flow with switch support.

Switch

C++ switch statements handle cases with break statements.

Loops

C++ loops use for while and do-while with break and continue.

Comments

C++ comments use // and /* */ for code documentation.

Errors

C++ errors use try-catch with exception classes.

Debugging

C++ debugging uses GDB or Visual Studio breakpoints.

Best Practices

C++ best practices include RAII, avoiding raw pointers.

Security Basics

C++ security prevents buffer overflows with safe practices.

Preprocessor

C++ preprocessor uses #include and #define for macros.

Namespaces

C++ namespaces organize code with using declarations.

Main Function

C++ main function is the entry point with int return.

Functions

C++ functions use typed parameters and return types.

Function Overloading

C++ function overloading uses different parameter types.

Default Arguments

C++ default arguments provide fallback values in functions.

Inline Functions

C++ inline functions optimize with inline keyword.

Lambda Expressions

C++ lambda expressions use [] for anonymous functions.

Function Pointers

C++ function pointers reference functions for callbacks.

Classes

C++ classes use class or struct with members.

Inheritance

C++ inheritance uses : for base class extension.

Polymorphism

C++ polymorphism uses virtual functions for runtime dispatch.

Abstract Classes

C++ abstract classes use pure virtual functions.

Interfaces

C++ interfaces use abstract classes with virtual methods.

Templates

C++ templates enable generic programming with type parameters.

Enums

C++ enums define constants with scoped enum class.

Arrays

C++ arrays are fixed-size typed collections with indexing.

Vectors

C++ vectors use std::vector for dynamic arrays.

Maps

C++ maps use std::map for key-value pairs.

Sets

C++ sets use std::set for unique elements.

Strings

C++ strings use std::string, with std::wstring for Unicode.

Pointers

C++ pointers use * and & for memory management.

References

C++ references use & for aliasing variables.

Smart Pointers

C++ smart pointers like unique_ptr manage memory safely.

Threads

C++ threads use std::thread for concurrent tasks.

Mutex

C++ mutex uses std::mutex for thread-safe access.

Async

C++ async uses std::async for asynchronous execution.

Condition Variables

C++ condition variables use std::condition_variable for synchronization.

File Reading

C++ file reading uses std::ifstream with error handling.

File Writing

C++ file writing uses std::ofstream with buffered streams.

File Paths

C++ file paths use std::filesystem for cross-platform handling.

File Deletion

C++ file deletion uses std::filesystem::remove with checks.

HTTP Server

C++ HTTP server uses libraries like Crow for web apps.

HTTP Client

C++ HTTP client uses libcurl or Boost for API calls.

JSON Handling

C++ JSON handling uses nlohmann/json for serialization.

JSON Parsing

C++ JSON parsing uses nlohmann::json with typed objects.

JSON Serialization

C++ JSON serialization uses nlohmann::json::dump with data.

WebAssembly

C++ WebAssembly compiles to WASM with Emscripten for web.

REST APIs

C++ REST APIs use Crow or Restbed with JSON responses.

WebSockets

C++ WebSockets use Boost.Beast for real-time apps.

Authentication

C++ authentication uses JWT for secure API endpoints.

Environment Variables

C++ environment variables use std::getenv for config.

SQLite

C++ SQLite uses sqlite3 library for local database queries.

PostgreSQL

C++ PostgreSQL uses libpqxx for typed queries.

MongoDB

C++ MongoDB uses mongocxx for document-based data.

Database Connections

C++ database connections use driver-specific APIs.

Logging

C++ logging uses spdlog or Boost.Log for structured logs.

Error Logging

C++ error logging captures exceptions with spdlog.

Request Logging

C++ request logging tracks API calls with custom handlers.

Testing

C++ testing uses Google Test or Catch2 with CMake.

Unit Testing

C++ unit testing uses assertions for function validation.

Integration Testing

C++ integration testing validates APIs with libcurl.

Mocking

C++ mocking uses Google Mock for isolated tests.

Benchmarking

C++ benchmarking uses Google Benchmark for performance.

REST API

C++ REST API with Crow handles CRUD with JSON responses.

WebAssembly App

C++ WebAssembly app compiles to WASM with Emscripten.

File Server

C++ file server serves static files with Crow.

Authentication API

C++ authentication API uses JWT for secure endpoints.

Database CRUD

C++ database CRUD with SQLite handles data operations.

Concurrent App

C++ concurrent app uses std::thread for parallelism.

API Testing

C++ API testing with libcurl validates REST endpoints.

Logging Setup

C++ logging setup with spdlog logs requests and errors.

Dockerized App

C++ Dockerized app uses Dockerfile for deployment.

Template Class

C++ template class implements generic data structures.
