C Template Class Function

Class templates are much like their sibling c template functions.

C template class function. The class c is a template with one parameter and the member function f is a template member function and you have to define it in the same way. Templates in c are classes and functions that can operate with generic types. The simple idea is to pass data type as a parameter so that we dont need to write the same code for different data types. I know its possible to make a template function.

Templates are the foundation of generic programming which involves writing code in a way that is independent of any particular type. For example you could make the templated stack class that can handle a stack of any data type rather than having to create the stack class for every different datatype for which you want the stack to function. The difference is that one class can take in many different data types. For example a software company may need sort for different data types.

Templated functions are actually a bit easier to use than templated classes as the compiler can often deduce the desired type from the functions argument list. If the declaration of the explicit instantiation names an implicitly declared special member function the program is ill formed. Template class x template class y void cxfy y something. Function templates are special functions that can operate with generic types.

Thats about the only difference practically. If you define the function at the declaration site youll implicitly declare it inline. C template class can be used for anything a regular class is able to do. In c this can be achieved using template parameters.

Templatetypename t void dosomethingt x and its possible to make a template class. This allows us to create a function template whose functionality can be adapted to more than one type or class without repeating the entire code for each type. Templatetypename t class object public. Explicit instantiation of a function template or of a member function of a class template cannot use inline or constexpr.

The compiler already tells you the answer. This term is a useful way to think about templates because it helps remind the programmer that a templated class does not depend on the datatype. A template is a blueprint or formula for creating a generic class or a function. A template is a simple and yet very powerful tool in c.

Templates can be used in conjunction with abstract data types to allow them to handle any data.
