Overview of this book

C++ is one of the most widely used programming languages. Fast, efficient, and flexible, it is used to solve many problems. The latest versions of C++ have seen programmers change the way they code, giving up on the old-fashioned C-style programming and adopting modern C++ instead. Beginning with the modern language features, each recipe addresses a specific problem, with a discussion that explains the solution and offers insight into how it works. You will learn major concepts about the core programming language as well as common tasks faced while building a wide variety of software. You will learn about concepts such as concurrency, performance, meta-programming, lambda expressions, regular expressions, testing, and many more in the form of recipes. These recipes will ensure you can make your applications robust and fast. By the end of the book, you will understand the newer aspects of C++11/14/17 and will be able to overcome tasks that are time-consuming or would break your stride while developing.

Using generic lambdas


In the preceding recipe, we saw how to write lambda expressions and use them with standard algorithms. In C++, lambdas are basically syntactic sugar for unnamed function objects, which are classes that implement the call operator. However, just like any other function, this can be implemented generically with templates. C++14 takes advantage of this and introduces generic lambdas that do not need to specify actual types for their parameters and use the auto specifier instead. Though not referred with this name, generic lambdas are basically lambda templates. They are useful in cases where we want to use the same lambda but with different types of parameter.

Getting started

It is recommended that you read the preceding recipe, Using lambdas with standard algorithms, before you continue with this one.

How to do it...

Write generic lambdas:

  • By using the auto specifier instead of actual types for lambda expression parameters.
  • When you need to use multiple lambdas that only differ...
