Answer:

We should always avoid including namespace and call the function followed by the namespace name. Let’s assume you want to display something on console then you should write the code in the below format,

std::cout << "Aticleworld.com";

The reason behind that it helps to avoid ambiguity when two included namespaces have the function of the same name.
