The Upcoming Features In C++17 Programming Language


C++ programming language is a multi-paradigm programming language with different features and capabilities. It is not possible to learn all the features of C++ in a single day or a month. It may take months or even years to get experts in C++ programming.

Though it is one of the oldest programming languages, it is still popular among programmers due to its powerful and rich standard library, the availability of compilers for almost every type of platform, and the capability to work with low-level memory manipulation.

C++ has been around for more than three decades. Still, it has managed to stay relevant and useful, thanks to its continuous evolution as a programming language. C++17 was released on 14th September 2017 as a major release in the C++ Programming Language Standards history after C++11 and C++14.

In this tutorial, we’ll have a look at the upcoming features in C++17 Programming Language.

With C++14, the language has got a lot of features added to it. The standard library also saw many new additions and improvements.

It was expected that C++17 will be the next major release after C++14. But now, it is expected that C++17 will only include small changes and improvements.

The ISO Standard Committee has proposed some new features for the upcoming C++17 programming language. We have discussed the top 10 upcoming features in this article.

In this article, we will discuss all the features proposed by ISO committee for C++17.

C++17 is the next evolution of the C++ programming language. The ISO Standard for C++17 is expected to be published in July 2017.

The International Organization for Standardization (ISO) has published C++98, C++03, C++11, C++14 and now C++17 as international standards.

In July 2015, the ISO approved the feature set for the upcoming version of the language – C++17. A draft International Standard for Programming Languages — C++ was released in March 2017 by ISO’s technical committee on programming languages (TC PL22.16).

There are many new features added in this version of the programming language. In this blog post, we will discuss a few of them.

The updated version of C++ programming language is going to be released in 2017. The new version is C++17. The features proposed for C++17 are aimed at improving usability, performance and developer productivity. This article discusses some of the upcoming features in C++17.

Before proceeding with the upcoming features, let’s see what’s new in the current stable version of C++ i.e., C++14 released in December 2014.

1)Variable Templates

2)Binary Literals

3)Generic lambdas

4)Aggregate Member Initialization

5)Lambda Capture by value or reference

6)Deleting functions (defaulted or deleted functions)

7)Return type deduction for normal functions etc.

On 14 December 2017, the ISO C++ committee published the final draft international standard of C++17. The committee has published a draft report (PDF) detailing all changes and improvements that have been made to C++17—the first major update to the language since 2014.

The new standard will be published in early 2018 and is expected to be available for widespread use by mid-2018.

The major feature of C++17 is support for parallelism via concurrency libraries. This makes it possible to take advantage of multicore systems without having to manage multiple threads directly.

The new standard also includes a number of smaller language features, as well as improved standard library functionality, including:

Structured bindings. Allows you to bind multiple variables to elements in a struct, array or tuple in one declaration.

Fold expressions. A simpler syntax for certain types of recursive variadic templates.

If constexpr. Adds a conditional compile step that can depend on template parameters.

Inline variables. Allows static member variables in headers to be defined inline with their declaration instead of separately at the end of the file.

The C++17 release is just around the corner and we are all excited about the new features it will bring. In this article, we take a look at some of the new features introduced in C++17.

C++17 is a major feature release and adds several new features to the C++ language. Before getting into the details of the features, let’s first look at how to get started with C++17.

The best way to get started with C++17 is by using GCC 7 or Clang 5.0 or higher. Almost all the new language features and library features are available in these compilers.

If you are on Ubuntu 17.04 or higher, you can install GCC 7 or Clang 5.0 by running:

sudo apt install g++-7 gcc-7 clang-5.0 lldb-5.0

If you are on MacOS, you can install Clang 5.0 by running:

brew install llvm

On Windows, you can use Visual Studio 2017 RC1 and later versions which come with support for many of the C++17 features.

The International Organization for Standardization (ISO) working group on the next revision of C++ met in Kona, Hawaii from February 20-28, 2016. The committee has decided to include many new features to the upcoming version of C++. This post is an attempt to provide a brief overview of these features.

I would like to start by mentioning that the upcoming version of C++ is expected to be named C++17. Although, this decision hasn’t been made so far and there is a chance that it may be named as C++1z.

Let’s have a look at some of the most important features that are going to be added in C++17:

1. Fold Expressions

C++17 will include Fold Expressions which allow programmers to write certain types of code more easily and efficiently. There are two types of fold expressions:

Unary Folds: These are used when there is only one parameter pack in the parameter list and that is at the rightmost side of the expression list. Binary Folds: These are used when there are more than one parameter packs in the parameter list or if they are not at the rightmost side of the expression list.

For example, consider two functions sum() and count().
