what is using namespace std and Why are we not using std::cout<<" "; format
Namespace std usage
@s.hashwanth531 In a program we night have many files attached to a program and few of them might have similar names, so as to avoid confusion and provide clarity. we can use name_of_the_space:: function to specify the function to be used.
Now we write
using namespace std;
So as to indicate that we will be using the “std” namespace, so after that as long as we are using things of “std namespace” we need not specify the namespace, it helps in reducing the code size.
If this resolves your doubt mark it as resolved.
