C++17
C++17 is released in 2017 with additional features which are not present in C++14 and also with improved features of C++14 which is constexpr. Key features of the C++17 standard are as follows:
- Structured Bindings: The ability to decompose structured objects into individual variables easily.
- if constexpr: This is a new feature introduced in C++ 17 that allows us to write conditional statements that are evaluated at the compile time.
- Fold Expressions: A concise syntax for expanding variadic templates and applying operators to template arguments.
- Parallel Algorithms in the STL: Standardized parallel algorithms for efficient execution on multi-core systems.
- Inline Variables: Inline variables can be defined in multiple translation units without violating the One Definition Rule (ODR).
- CTAD: This is the feature introduced in C++17 that is used to deduce template arguments for a class template from its constructor arguments.
- Nested Namespaces: In C++17 we can create namespaces within other namespaces.
- Variable declaration in if and switch: In C++17, we can declare and initialize variables directly within if and switch statements.
C++ Standards and Implementations
C++ programming language is widely used and known for its power, versatility, and performance. C++ is an extension of the C programming language created by Danish computer scientist Bjarne Stroustrup. With time several C++ standards have been introduced with new features and enhancements. In this article, we will explore the major C++ standards, along with their key features to understand the evolution of C++ and the benefits provided to programmers or developers.
Nowadays C++ is popular for competitive programming because of its performance but it is also used for building robust applications which we are using in our daily life. A few of them are given below:
- Operating Systems
- Games
- Embedded Systems
- Compilers
- Web Browsers
