What is templating in programming?

Templates are the foundation of generic programming, which involves writing code in a way that is independent of any particular type. A template is a blueprint or formula for creating a generic class or a function.

What is Template metaprogramming used for?

Template metaprogramming (TMP) is a metaprogramming technique in which templates are used by a compiler to generate temporary source code, which is merged by the compiler with the rest of the source code and then compiled.

What does TMP stand for in C++?

Template meta-programming (TMP) refers to uses of the C++ template system to perform computation at compile-time within the code. It can, for the most part, be considered to be "programming with types" — in that, largely, the "values" that TMP works with are specific C++ types.

Are templates compile-time?

Template specialisation (partial or full) is a compile-time if. Let me be more specific: When I use removeConst with a non-constant int (line 1), the compiler chooses the primary or general template (line 2). When I use a constant int (line 3), the compiler chooses the partial specialisation for const T (line 4).

What are C++ templates used for?

Templates are powerful features of C++ which allows you to write generic programs. In simple terms, you can create a single function or a class to work with different data types using templates. Templates are often used in larger codebase for the purpose of code reusability and flexibility of the programs.

How are templates useful?

The idea behind the template is that it is a guide or model that can be reproduced. When it comes to Office, templates are basic documents with some elements like formatting and even content in place. Their main purpose is to help you get started, or take the time out of beginning certain tasks.

Which are done by compiler for templates?

Which are done by compiler for templates? Explanation: The compiler can determine at compile time whether the type associated with a template definition can perform all of the functions required by that template definition. 9.

Is C++ metaprogramming useful?

I use metaprogramming all the time in my job. It's a powerful tool which can be used to do a lot of things in a more readable and maintainable way. ... It's fine to have an opinion that metaprogramming is good. It's fine to have an opinion that we should all aspire to be better C++ developers.

Is same type C++?

The std::is_same template of C++ STL is used to check whether the type A is same type as of B or not. It return the boolean value true if both are same, otherwise return false.

What is string tmp?

tmp is the data structure over which you want to iterate. string str is the declaration that will be called for each elements in the data structure. The type declared should reflect what is in the data structure. This str variable will give you access to the data structure's item in the loop's "body".

What is static metaprogramming?

Static metaprogramming (i.e. Annotation Processing) allows us to intersect the compiler, which already does most of the things we try to accomplish with reflections. We can also create classes in this process, which are again passed to the annotation processors.

Which function is used to reposition the file pointer?

Which function is used to reposition the file pointer? Explanation: seekg() function is used to reposition a file pointer in a file.
