Hello again awesome team of coders......

I know using (preprocessor?) 'using namespace std;' gives same result that 'std::count/std::cin' but since I noticed both syntax are used in books I wonder what is consider 'best practice' on this regard?

Also noticed that some code editors (like atom, for example) default to 'std::...' syntax even if 'using namespace std' has been specified so I'm curious about what should be the more appropriate?

Thanks.
