I am learning C++ and in my book using namespace std is written in every program. I understand that std::cout <<"hello"; can be simply written as cout << "hello"; by using namespace std.

Why?

      I don’t blame beginners for using it. So many starter guides show using namespace std; without even explaining it or its pitfalls.

      All I can say is to get used to writting std::
      It’s not really that much work, and makes it more obvious where some calls are coming from for any readers of your code.
