In c++ i can write const int const* for a constant pointer to an constant int. I can also write const int& for a const reference. So is const int const& a reference to a const int?
(1) One can extract the return type and the argument types of a callable with the following trait:(2) Since C++17, one can define a template with template<auto>:
I am working through the exercises in the book "Learn C the hard way". Exercise 7 asks the reader to find the value which makes the range of an unsigned long exceed.
I would like to parse a file and determine if the number I've read is float or double. The file I parse is one of the matrices in Matrix Market format (like this: https://sparse.tamu.edu/HB/1138_bus).
Consider a randomly generated __m256i vector. Is there a faster precise way to convert them into __m256 vector of floats between 0 (inclusively) and 1 (exclusively) than division by float(1ull<<32)?
Inspired from this answer, which claims to subvert the access control system, I wrote the following minimal version of the hack
If in theory imagine a situation where, by chance or by mistake (either through carelessness, or due to lack of experience, etc.), the memory was freed twice using delete-exprssion (yes, a good developer will not allow this, in well-designed architectural solutions, but howewer) how to (can we, or is there...
When learning more about the standard event model in .NET, I found that before introducing generics in C#, the method that will handle an event is represented by this delegate type:
vs Though both of the above examples store 3 in j, is there a difference between how the above two cases are evaluated?
I've been optimising/benchmarking some code recently and came across this method:This is called from a performance critical loop elsewhere, so I naturally assumed all those typeof(...) calls were adding unnecessary overhead (a micro-optimisation, I know) and could be moved to private fields within the class. (I'm aware there are better...
