What are the new features in C++17?

C++17 includes the following new language features:

• template argument deduction for class templates.
• declaring non-type template parameters with auto.
• folding expressions.
• new rules for auto deduction from braced-init-list.
• constexpr lambda.
• lambda capture this by value.
• inline variables.
• nested namespaces.

Which feature is not available in C++17?

But this is not the case, as “std::pair” is a standard template library class. Whereas the template classes cannot allow type deduction during initialization. Now it is possible to compile the above source code under C++17 language conformant compiler….Fold expressions.

Operator	Default values
,	void()
||	false

Which is better C++ or C++14?

You can clearly see that C is much faster than C++14 but the thing to notice is that when using that modification(boost) it can be clearly seen that C++14 and C++ outperforms C in their execution time (in case of large test cases).

What are the five best features of C++?

What features make C++ powerful?

C++ is the most-efficient and powerful language because of its high-level functionalities. The main 4 pillars of C++ are Abstraction, Encapsulation, Inheritance, and Polymorphism.

Is C11 better than C99?

It replaced C99 (standard ISO/IEC 9899:1999) and has been superseded by C17 (standard ISO/IEC 9899:2018). C11 mainly standardizes features already supported by common contemporary compilers, and includes a detailed memory model to better support multiple threads of execution.

What was introduced in C++ 11?

The C++11 Standard Library was also revamped with new algorithms, new container classes, atomic operations, type traits, regular expressions, new smart pointers, async() facility, and of course a multithreading library. A complete list of the new core and library features of C++11 is available here.
