Complete Modern C++ - Lambda Expressions

The video tutorial introduces Lambda expressions, explaining their role as anonymous function objects and their ability to replace function objects in many cases. It covers the structure of Lambda expressions, including the Lambda introducer, capture clause, arguments, and return type. The tutorial also demonstrates how to implement Lambda expressions in Visual Studio, showing how they can be used as function objects and how to assign them to variables using the auto keyword.

What is a Lambda expression primarily used for?

• To overload operators

• To replace all function pointers

• To define anonymous function objects

• To create named functions

How does the compiler handle a Lambda expression internally?

• It ignores the Lambda expression

• It generates a class with an overloaded function call operator

• It creates a named function

• It converts it into a function pointer

What keyword is used to assign a name to a Lambda expression?

• auto

• const

• var

• let

Which part of a Lambda expression specifies the start of the expression?

• Mutable specification

• Capture clause

• Lambda introducer

• Trailing return type

What is the purpose of the trailing return type in a Lambda expression?

• To make the Lambda expression mutable

• To specify the return type of the Lambda expression

• To define the parameters of the Lambda expression

• To capture external variables
