Multi-Paradigm Programming with Modern C++ - Going Functional

The video tutorial introduces a problem of finding a rectangle with an area closest to a reference value. It highlights the limitations of using simple loops and suggests using function objects and lambda expressions for more flexibility and less code duplication. The tutorial explains lambda expressions, their syntax, and advantages, including the trailing return syntax and capture block. It also covers generic lambda expressions and their benefits in simplifying code.

What is a major drawback of using a simple loop to find the rectangle with the nearest area to a reference value?

• It is not compatible with modern programming languages.

• It requires advanced mathematical knowledge.

• It lacks flexibility and leads to code duplication.

• It is too fast.

What is the primary advantage of using the 'min_element' algorithm over a simple loop?

• It automatically finds the largest element.

• It requires no input from the programmer.

• It is only available in certain programming languages.

• It allows for custom criteria to find the smallest element.

How do lambda expressions improve upon traditional function objects?

• They are slower but more reliable.

• They require more boilerplate code.

• They offer a more compact syntax and reduce boilerplate code.

• They are only used in legacy systems.

What is a key feature of lambda expressions that makes them preferable to function objects?

• They are not supported in modern compilers.

• They automatically optimize code.

• They allow for a compact syntax with capture blocks.

• They can only be used once.

What is a potential risk when using lambda expressions with captured references?

• They can lead to memory leaks.

• They cannot be used with shared pointers.

• They are always slower than traditional loops.

• They might cause undefined behavior if the object is deleted.

Why should default capture mode in lambda expressions be avoided?

• It captures too many variables, making code harder to read.

• It is not supported in most programming languages.

• It requires additional memory allocation.

• It simplifies the code too much.

What is the benefit of using 'auto' in lambda expressions?

• It restricts the lambda to a single data type.

• It allows for generic lambda expressions without specifying argument types.

• It is only useful in legacy code.

• It makes the code less readable.
