"Transforming your struggles into success"

`using namespace std` in C++ allows direct access to the standard library's features (like `cout`, `cin`) without needing to prefix them with `std::`.

The std namespace in C++ contains many standard library components, including data types, functions, and objects. When you write using namespace std;, you're essentially telling the compiler to consider all the names in the std namespace as if they're in the global namespace.
