WebGCC limits N to 900, unless you add the -ftemplate-depth= compiler option. See this bug. Clang limits N to a pathetic 256, but also provides the same -ftemplate-depth= option. To solve the problem, std::make_integer_sequence can be implemented in O (log (N)). I have done this as follows: WebThis code is not very readable, take a look on this which is C++ and it is written to be more readable. Basically algorithm is same, but information is not stored in bits (there is no point in case constexpr). Change std::array to std:vector and you have version, where flags are stored in single bits. – Marek R May 21, 2024 at 9:35 1

WebFeb 8, 2011 · This may ideally depend on the language you'll be using (this uses C and C++), but it may be good to use 1 (or EXIT_FAILURE) for this. Finally, you can just have process 0 display the error so that it's displayed only once (any normal output should just be printed by this process). WebMay 20, 2014 · In C++, it's a good habit to prefer prefix increment- and decrement-operators, because they are usually more efficient for non-built-in types. It doesn't really matter for built-in types, but consistency is nice. Consider using using -declarations, i.e. using std::vector; and so on, to make the code more readable.
