Given an example:
double values[] {2.5, -3.5, 4.5, -5.5, 6.5, -7.5};
std::vector<double> squares(std::end(values) - std::begin(values));
std::transform(std::begin(values), std::end(values), std::begin(values), std::begin(squares), [](double x1, double x2) throw() { retu x1 * x2; });1) Is this functional equivalent to:
[](double x1, double x2) noexcept { retu x1 * x2; })?
2) Is there a convincible reason, why should I mark such expression (or similar basic expresions) with either modifiers or in this case, it is better to leave it and simply don't bother?
