There is a good article on it on stack overflow

Although if you are doing coding for school or college don't bother using std again and again.

Just use "using namespace std;"

the 10 cent summary of the article is that std:: is huge beyond control and it is too easy to accidentally reuse common words that it defines, causing problems, eg min and max and many other common variable name candidates are defined in it.

you can use bits of it, eg using std::cout
