agentic AI system almost solved how to speed up a push_back() loop,
here's the slightly improved version of the result:
ALT std::vector<std::string> parse(std::input_iterator auto begin, std::input_iterator auto end) { std::vector<std::string> parsed; parsed.reserve(parsed.max_size()); for (; begin != end; ++begin) parsed.emplace_back(parseDataPoint(*begin)); return parsed; }

Слова «C++» и «JSON» нечасто встречаются в одном названии.
Но тем интереснее послушать такой доклад, и в этот #плюсочетверг открываем его запись: youtu.be/-JjE5AhfhcM

ALT Helpful tip Write constructor and destructor for promise types. ```c++ template<typename T> struct Promise { Promise() { std::cout << "Promise: ctor\n"; } ~Promise() { std::cout << "Promise: dtor\n"; } //... ```
if(((x==42)||...))
error: equality comparison with extraneous parentheses [-Werror,-Wparentheses-equality]
...
note: remove extraneous parentheses around the comparison to silence this warning
ok
if((x == 42||...))
error: expression not permitted as operand of fold expression
