Explore the evolution and specifications of the C++ programming language.

Key C++ Standards

Understanding C++ Standards

The C++ standard is developed by the ISO/IEC JTC1/SC22/WG21 committee. It defines the syntax, semantics, and library for the C++ programming language. Each standard represents a snapshot of the language's evolution, incorporating new features, improvements, and bug fixes.

Why Standards Matter

Adhering to standards ensures portability and interoperability of C++ code across different compilers and platforms. They provide a stable foundation for developers and tool vendors, fostering a robust ecosystem.

Key Areas Covered

Resources and Links

Official standards are typically available for purchase from ISO and national standards bodies. However, many drafts and final publications are made accessible through academic or developer resources.

Example: C++20 Features

// C++20 Coroutine Example Snippet
#include 
#include 

struct task {
    struct promise_type {
        auto get_return_object() { return task{}; }
        auto initial_suspend() { return std::suspend_always{}; }
        auto final_suspend() noexcept { return std::suspend_always{}; }
        void return_void() {}
        void unhandled_exception() {}
    };
};

task counter(int max) {
    for (int i = 0; i < max; ++i) {
        std::cout << i << std::endl;
        co_await std::suspend_always{}; // Suspend and resume later
    }
}

int main() {
    counter(5); // This will suspend and print numbers
    // Actual resumption logic would be needed in a full example
    return 0;
}
