C++ Ecosystem and Tools

Debugging tools: GDB, LLDB
Code analyzers: cppcheck, clang-tidy
Build systems: CMake, Make
Package managers: Conan, vcpkg

Memory Management Best Practices

Manual memory management vs. smart pointers
Avoiding memory leaks and using RAII (Resource Acquisition Is Initialization)
Stack vs. heap memory allocation

Unit Testing in C++

Writing and organizing unit tests using GoogleTest or Catch2
Introduction to Test-Driven Development (TDD) in C++

Example:

TEST_F(EmployeeTest, SalaryTest) {
    Employee emp("John", 1000);
    EXPECT_EQ(emp.getSalary(), 1000);
}

C++ and Multithreading

Threading libraries: <thread>, OpenMP, TBB
Synchronization techniques: mutexes, semaphores, and avoiding race conditions

Example: Multithreaded processing with a mutex

std::mutex mtx;
void safe_print(const std::string &msg) {
    std::lock_guard<std::mutex> lock(mtx);
    std::cout << msg << std::endl;
}

Code Profiling and Performance Tuning

Tools for profiling: Valgrind, gprof
Techniques for optimizing CPU cycles and reducing memory footprint
Example: Using Valgrind to detect memory leaks:
```
valgrind --leak-check=full ./my_program
```

Cross-Platform Development

Writing cross-platform C++ code using platform-specific APIs like POSIX and Windows API
Cross-compilation using CMake and Docker

Continuous Integration (CI) for C++ Projects

Setting up CI pipelines with GitHub Actions or Jenkins for automated building and testing

Example: GitHub Actions C++ build pipeline

name: C++ CI

on: [push]

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - name: Set up C++
        uses: actions/setup-cpp@v1
        with:
          compiler: gcc
      - run: cmake .
      - run: make

Formatting Enhancements

Add Links to Resources
- Official C++ Documentation
- CMake Documentation

Add Code Blocks

Provide code snippets throughout to make the content more interactive, like:

class Person {
private:
    std::string name;
public:
    Person(std::string n) : name(n) {}
    void introduce() { std::cout << "Hi, I'm " << name << std::endl; }
};

Visual Aids

Use Mermaid diagrams to explain concepts like inheritance or program flow:

classDiagram
    Person <|-- Employee
    Employee <|-- Manager
    class Person {
      +string name
      +introduce()
    }
    class Employee {
      +int salary
    }
    class Manager {
      +int teamSize
    }
