In C++ specifies constructors and conversion operators that don't allow implicit conversions or copy-initialization. In C# declares a user-defined type conversion operator that must be invoked with a cast. For MS SQL Server for-xml-EXPLICIT mode use the [for-xml-explicit] tag

void foo(X a = X()){}
int main(){}
Using C++14 standard, both GCC 7.1 and clang 4.0 rejects the code, which is what I expected.
However, using C++17 (-std=c++1z), they…

Best (safest) way to convert from double to int
I'm curious as to the best way to convert a double to an int. Runtime safety is my primary concern here (it doesn't necessarily have to be the fastest method, but that would be my secondary concern). I've left a few options I can come up with…

transform results" or…

How to calculate the explicit form of a recursive function?
I have this recursive function:
f(n) = 2 * f(n-1) + 3 * f(n-2) + 4
f(1) = 2
f(2) = 8
I know from experience that explicit form of it would be:
f(n) = 3 ^ n - 1 // pow(3, n) - 1
I wanna know if there's any way to prove that. I googled a bit, yet…

Today I happens to find that one C# class can inherit one interface both in implicit and explicit way. This surprises me. If C# works in this way, then one instance can behave differently when referenced in different way.
