I am learning C++ and in my book
using namespace stdis written in every program. I understand thatstd::cout <<"hello";can be simply written ascout << "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.
