// ✅ Функция работает с ЛЮБЫМ непрерывным контейнером! void processData(std::span<const int> data) { for (const auto& item : data) { // Обработка } }
int main() { // Работает с std::vector std::vector<int> vec = {1, 2, 3, 4, 5}; processData(vec);
// Работает с std::array std::array<int, 3> arr = {10, 20, 30}; processData(arr);
// Работает с C-массивами int classic[] = {100, 200, 300}; processData(classic);
// Работает с подпоследовательностями! processData(std::span(vec).subspan(1, 3)); // Только элементы 2,3,4 }
❗️Преимущества std::span:
- Не владеет данными (zero overhead) - Безопасно передает подпоследовательности - Унифицированный интерфейс для всех контейнеров - Выразительный код без шаблонных параметров

The SSE was the first modern stock exchange to open in China, with trading commencing in 1990. It has now grown to become the largest stock exchange in Asia and the third-largest in the world by market capitalization, which stood at RMB 50.6 trillion (US$7.8 trillion) as of September 2021. Stocks (both A-shares and B-shares), bonds, funds, and derivatives are traded on the exchange. The SEE has two trading boards, the Main Board and the Science and Technology Innovation Board, the latter more commonly known as the STAR Market. The Main Board mainly hosts large, well-established Chinese companies and lists both A-shares and B-shares.
That strategy is the acquisition of a value-priced company by a growth company. Using the growth company's higher-priced stock for the acquisition can produce outsized revenue and earnings growth. Even better is the use of cash, particularly in a growth period when financial aggressiveness is accepted and even positively viewed.he key public rationale behind this strategy is synergy - the 1+1=3 view. In many cases, synergy does occur and is valuable. However, in other cases, particularly as the strategy gains popularity, it doesn't. Joining two different organizations, workforces and cultures is a challenge. Simply putting two separate organizations together necessarily creates disruptions and conflicts that can undermine both operations.
