Complete Modern C++ - Namespace

The video tutorial explains the concept of namespaces in C programming, highlighting their role in preventing name clashes and modularizing code. It covers how to create and use namespaces, including nested and unnamed namespaces, and demonstrates accessing types within namespaces using global using declaratives and fully qualified names. Examples illustrate how namespaces can resolve naming conflicts and group related functions, enhancing code structure and readability.

What is the primary purpose of a namespace in C?

• To simplify memory management

• To increase the execution speed of a program

• To prevent name clashes and modularize code

• To enhance the graphical user interface

Which statement is used to open an entire namespace in C?

• namespace

• using namespace

• include

• import

What is a potential downside of opening an entire namespace?

• It makes the code harder to read

• It slows down the program execution

• It may cause all types to become visible, leading to conflicts

• It can lead to increased memory usage

How can you access a specific type from a namespace without opening the entire namespace?

• By using the 'export' statement

• By using the full qualified name

• By using the 'include' directive

• By using the 'import' statement

What is the benefit of using namespaces to organize functions?

• It automatically optimizes the functions

• It allows functions to run faster

• It reduces the size of the code

• It groups related functions together, improving code structure

What is a nested namespace?

• A namespace that is defined within another namespace

• A namespace that contains only one type

• A namespace that is used only for debugging

• A namespace that is automatically generated by the compiler

What is the purpose of an unnamed namespace?

• To make types visible only within the file it is declared

• To allow types to be accessed globally

• To improve the performance of the program

• To automatically resolve name clashes
