What is template specialization and how it can be used?
Template in C++is a feature. We write code once and use it for any data type including user defined data types. For example, sort() can be written and used to sort any data type items. It is possible in C++ to get a special behavior for a particular data type. This is called template specialization.
Why do we need templates in C++?
Templates are very useful when implementing generic constructs like vectors, stacks, lists, queues which can be used with any arbitrary type. C++ templates provide a way to re-use source code as opposed to inheritance and composition which provide a way to re-use object code.
What is full specialization?
Explicit (full) specialization Allows customizing the template code for a given set of template arguments.
What is the other name of full specialization?
Explanation: explicit specialization is another name of full specialization.
Which are done by compiler of templates?
Instantiation is the process by which a C++ compiler creates a usable function or object from a template. The C++ compiler uses compile-time instantiation, which forces instantiations to occur when the reference to the template is being compiled. Template instantiations are always up-to-date.
What is the need of templates?
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.
Why do we need templates?
Templates basically enforce overall consistency by having a pre-determined structure and layout. All documents made using a template will match its layout exactly. When it comes to your document’s content, Word’s Styles tool is a great way to maintain consistent formatting.
