#include <cmath>
#include <iostream>
template<typename T, std::size_t N>
auto norm(const std::array<T, N>& arr)
-> T
{
T res{};
for (auto value: arr)

I often write such methods to avoid duplication in code and I give them name such as doSomethingIfSomeCondition().
For example:

public TaskDownloadFile () {
started = false;
}
public boolean isStarted() {

These IDs seem like they should be a table as there are several queries that use the same list of IDs. The following needs to be refactored.
SELECT SUM(CASE WHEN s.TypeID IN(1,2,3,4,7,8,10) THEN 1 ELSE 0 END) FROM Sales s
The problem is a subquery can't be used in an aggregate function. The ...

I basically check that in all cases in my remove. Is there any way I can avoid thi...
