This article mainly introduces "why the interface in C++ is a template type, use concept to document its parameters". In daily operation, I believe that many people have doubts about why the interface is a template type in C++ and use concept to document its parameters. The editor consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the question of "why the interface in C++ is a template type, use concept to document its parameters"! Next, please follow the editor to study!

Reason (reason)

Make the interface precisely specified and compile-time checkable in the (not so distant) future.

This allows the interface to be accurately defined and can be checked at compile time in the future.

Example (sample)

Use the ISO Concepts TS style of requirements specification. For example:

Use requirements definitions in ISO Concepts technical specification style, such as:

Template// requires InputIterator & & EqualityComparable, Val > Iter find (Iter first, Iter last, Val v) {/ /...}

Note (Note)

Soon (probably within 2018), if you remove the "/ /" from the code, many compilers will be able to check the requires clause. Concepts will be supported in GCC6.1 and later versions.

At this point, the study on "why the interface in C++ is a template type uses concept to document its parameters" is over. I hope I can solve your doubts. The collocation of theory and practice can better help you learn, go and try it! If you want to continue to learn more related knowledge, please continue to follow the website, the editor will continue to work hard to bring you more practical articles!
