C++ Modules: From “Need to Have” to “Nice to Have” feature.

The introduction of modules in C++ marks a significant shift in the language’s approach to code organization and compilation. Initially seen as a much-needed feature to address the limitations of the traditional header/include model, modules have evolved into a feature that, while beneficial, is often considered “nice to have” rather than essential for many developers. This detailed post explores the journey of C++ modules from a critical need to a desirable but not universally prioritized feature.

It was obvious that C++ would be blamed for the CrowdStrike big outage.

Latest Friday , BANKS, AIRPORTS, TV stations, healthcare organizations, hotels, and numerous other businesses are experiencing widespread IT outages, leading to grounded flights and extensive disruption, as Windows machines have encountered errors globally. And we wrote a post explaining that soon they would blame C++ for that, and that is exactly what is happening, as we can see here.

Please don’t tell us that the Huge Microsoft Outage Linked to CrowdStrike is also a C++ code fault

Recently, a wave of criticism has been directed at C++, with some companies, organizations and websites labeling it as the “evil language” responsible for a significant portion of software vulnerabilities and damage. This criticism, however, stems from a fundamental misunderstanding of the nature of programming languages and software development. It’s essential to delve deeper into this issue to clarify that the problems attributed to C++ are not inherent to the language itself, but rather a consequence of how it is used.

Today, BANKS, AIRPORTS, TV stations, healthcare organizations, hotels, and numerous other businesses are experiencing widespread IT outages, leading to grounded flights and extensive disruption, as Windows machines have encountered errors globally.

Meeting C++ might be your top resource for staying updated with C++

Staying updated about C++ is crucial for keeping up with new features, best practices, and community discussions. There are some useful links to help you stay current with the latest in C++, like the ISO C++ website.

As C++ tool editors, it is essential for us to stay up to date with the latest developments in C++. Meeting C++ channels, including their website, Twitter, and LinkedIn, are crucial and valuable resources for receiving timely news and updates about C++. Indeed The Meeting C++ website is offering a variety of content and opportunities to engage with the C++ community. Here’s an overview of what you can find on the Meeting C++ website:

C++ optimization is more about design choices.

In C++ programming, optimization goes beyond just tweaking code for performance gains. It fundamentally revolves around making smart design choices. Here’s why:

Algorithm Selection: The choice of algorithm can drastically affect performance. Using an O(n log n) sort algorithm over an O(n^2) one is a prime example.
Data Structures: Choosing the right data structure (e.g., using a hash table instead of a linked list for fast lookups) can lead to significant efficiency improvements.
Memory Management: Efficient memory usage and minimizing allocations/deallocations can enhance performance. Techniques like memory pooling or using smart pointers properly can make a big difference.
Concurrency and Parallelism: Designing systems that effectively use multiple threads or processes can improve performance. C++11 introduced standard support for threading, which aids in this.
Avoiding Premature Optimization: Focusing on clean, maintainable code first and optimizing critical sections later is usually more effective.

How advanced C++ developers wrote modern code before the rise of modern standards.

Before the advent of C++11 and subsequent standards, advanced C++ developers had to innovate to write modern, maintainable, and efficient code. Here are some examples of how they proceeded with features that were later standardized:

Abstracting technical layer details in C++ to mitigate the language’s learning curve.

Recently, I came across a LinkedIn post showing a C++ developer’s reaction to seeingfor the first time how array sorting is done in Python. Unsurprisingly, the simplicity of Python’s approach was shocking.

arr=[64,12,22,55,44]
bubble_sort(arr)
print("Sorted Array:",arr)

7 Tips to improve the C++ algorithms complexity (Big-O)

Understanding algorithm complexity, specifically Big-O notation, is crucial for analyzing and comparing the efficiency of algorithms. In C++, as in other programming languages, the complexity of an algorithm can significantly impact the performance and scalability of an application. So it’s useful to know how to improve the algorithm complexity. But before that let’s explore the most common algorithm complexities:
