I want to define an effective whole floor function, i. e. A float or double conversion, which truncates to minus infinity. Can you imagine ideas to increase your performance in terms of speed, accurac

I need to implement many derived classes with different constant member data. Data processing should be in the base class, but I can not find an elegant way to access the derived data. The following c

It’s almost a factor two faster than the sum. And since the integrated sum should be about five times faster than manually adding a list (depending on the answer), it means that it is actually ten ti

If you use the same code, simply change the compiler (from a C compiler to a C ++ compiler) to change the amount of memory allocated. I do not know why and I would like to understand better. So far, t

I am from Python and I am currently learning C ++. I learned a C / C ++ function called memset and found the compile time errors. When I give t in single quotes to print it gives repetitive t’s?

I need an STL algorithm that uses a predicate and a collection and returns true if only one member of the collection satisfies the predicate, otherwise returns false.How could I do that with STL algor

Why are dynamic mappings or exceptions not recommended in environments subject to high radiation, such as in space or in a nuclear power plant? As for the models, I do not understand why. Can you expl

I was using std::string as a buffer and one of my friend noticed and said there are downsides of using std::string. If this is so then what is the problem in using std::string?

I was using git bash during my programming. I am tired of writing git before each and every command I want to execute. How can I stop using git before each and every command I wish to execute?

By the overview of software technologies, languages and frameworks are also presented instantaneously to program them. Currently, JavaScript and its several bases are extensively used by Full Stack De
