Complete Modern C++ - Lambda Expressions Capture List - Part III

The video tutorial explains Lambda expressions, focusing on capturing local, global, and static variables. It demonstrates creating a product clause with price and tax calculations using Lambda expressions. The tutorial covers using Lambda expressions in member functions, capturing variables, and nested Lambda expressions. It also explains how Lambda expressions can be used as function pointers, highlighting their flexibility and conversion process.

What is the primary purpose of using a Lambda expression in the context of the product class?

• To print the product's details

• To store the product's base price

• To calculate the final price including taxes

• To initialize the product's name

How are member variables captured in a Lambda expression within a class?

• By capturing them by reference

• By using the 'this' pointer

• By capturing them by value

• By using a global variable

What is demonstrated by the example of nested Lambda expressions?

• How to initialize a class

• How to capture global variables

• How to double a value before passing it

• How to print a string

What happens when a Lambda expression does not have a capture list?

• It captures all local variables by default

• It throws a compilation error

• It automatically decomposes to a function pointer

• It cannot be used as a function pointer

Why is an empty capture list important for using Lambda expressions as function pointers?

• It prevents memory leaks

• It enables the type conversion operator

• It allows the Lambda to be used in C++ only

• It simplifies the syntax

What is the role of the type conversion operator in Lambda expressions?

• To convert a Lambda into a class

• To convert a Lambda into a function pointer

• To convert a Lambda into a string

• To convert a Lambda into an integer

What error occurs if a Lambda expression with a capture list is used as a function pointer?

• Memory allocation error

• Runtime error

• Conversion error from function object to C style function

• Syntax error
