Multi-Paradigm Programming with Modern C++ - Passing Things Around

The video tutorial discusses various methods of passing data in programming, focusing on C language. It covers ground rules for passing arguments, emphasizing the importance of keeping argument numbers low and managing memory explicitly. The tutorial explains conventional ways of passing information, such as by value, constant reference, and rvalue reference, and advises against using out arguments. It also highlights the use of smart pointers for managing heavy objects and discusses copying and moving arguments. Finally, it warns against using raw pointers due to potential issues and suggests better alternatives.

Which of the following is NOT a method of passing data in C?

• By constant array

• By constant pointer

• By constant reference

• By value

What is the recommended maximum number of arguments for a function to maintain simplicity?

• 2

• 6

• 4

• 8

Why should you avoid relying on interfaces of other packages in your interface design?

• It might expose implementation details

• It makes the code run faster

• It increases the number of arguments

• It simplifies the code

What is the default method for passing arguments when a copy is cheap?

• By pointer

• By constant reference

• By value

• By reference

What is a better alternative to using out arguments in a function?

• Using a global variable

• Using a return statement

• Using a raw pointer

• Using a constant pointer

What is a major downside of using raw pointers?

• They are too complex

• They are ambiguous

• They are too fast

• They are too simple

When is it acceptable to use raw pointers?

• When using a legacy API

• When using a constant reference

• When using a smart pointer

• When using a modern API
