Question

Which of the following techniques can you not use to make the members of the std namespace available to your code? a. Code a using directive for the namespace b. Code an include preprocessor directives for the members c. Identify the members using fully qualified names d. Code a using declaration for each member

Answer 1

Answer:

b. Code an include preprocessor directives for the members

Explanation:

Namespace in programming can be defined as the declarative region which provides scope for the identifiers such as the functions, name of the types, variables, etc.

The namespaces are $\text{used to organize}$ the code into the logical groups and also used to prevent the name collision.

The ways that can be used outside the namespace $\text{can access the members}$ as :

-- the code used the fully qualifies name

-- by using the declaration to bring one of the identifier into the scope

-- by using the directive to bring all the things in the newspaper into the scope.

Thus the correct option is (b).
