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?

Correct. While using the namespace saves some time when writing (and some space when printing), it may lead to excess time used debugging later when a name clash happens.
The last point might not be a concern for small “toy programs” used for educational purposes. It is still bad style and should be avoided, especially for toy programs used for educational purposes, though.
