How do I restrict a template type in C++?
There are ways to restrict the types you can use inside a template you write by using specific typedefs inside your template. This will ensure that the compilation of the template specialisation for a type that does not include that particular typedef will fail, so you can selectively support/not support certain types.
What is meant by template parameter in C?
Function templates are special functions that can operate with generic types. A template parameter is a special kind of parameter that can be used to pass a type as argument: just like regular function parameters can be used to pass values to a function, template parameters allow to pass also types to a function.

What is the purpose of templates in C + +?
C++ Templates. 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.
Can a template be used to define a class?
You can use templates to define functions as well as classes, let us see how they work − The general form of a template function definition is shown here − Here, type is a placeholder name for a data type used by the function. This name can be used within the function definition.
How many copies of static variables are there in a template?
Each instantiation of class template has its own copy of member static variables. For example, in the following program there are two instances Test and Test. So two copies of static variable count exist. Please write comments if you find anything incorrect, or you want to share more information about the topic discussed above.
