A heterogeneous container in c.
Container as template parameter c. A function parameter pack is a function parameter that accepts zero or more function arguments. A type parameter is defined following the keyword class or typename. Acts a synonym for the template parameter ty. In c this can be achieved using template parameters.
A nontype parameter is declared following a type specifier. For more information see c standard library containers. We must still use a visitor pattern. It s the name of a class template that has a single type name parameter.
All such template parameters in the program of the same type with the same value denote the same template parameter object. The second parameter cont is a template template parameter. It is one of the most important features of c and will form the basis of all ongoing quantitative finance programs within this book. Let s begin with a feature that was added in c 14.
We can never be as flexible as a duck typed language such as python. C standard template library part i containers the standard template library stl is a cross platform standard of efficient data structures and algorithms. The only meaning we can ascribe to a template parameter is to distinguish whether the parameter is a type parameter or a nontype parameter. A template parameter pack is a template parameter that accepts zero or more template arguments non types types or templates.
A template with at least one parameter pack is called a variadic template. These function templates can use these parameters as if they were any other regular type. If it is a type parameter then we know that the parameter represents an as. 3 3 9 template parameter scope 3 3 9 1 the declarative region of the name of a template parameter of a template template parameter is the smallest template parameter list in which the name was introduced.
A template parameter is a special kind of parameter that can be used to pass a type as argument. We cannot create new types at runtime and add them to our container and we can t easily iterate over the container. This topic is in the microsoft c documentation as a nonfunctional example of containers used in the c standard library. Note that we didn t give a name to the type name parameter of cont although we could have.
