The templates defined so far have had types as the parameters of the template, but you can also provide integer values. The following is a rather contrived example to illustrate the point:
template<int size, typename T> T* init(T t) { T* arr = new T[size]; for (int i = 0; i < size; ++i) arr[i] = t; return arr; }
There are two template parameters. The second parameter provides the name of a type where T is a placeholder used for the type of the parameter of the function. The first parameter looks like a function parameter because it is used in a similar way. The parameter size can be used in the function as a local (read-only) variable. The function parameter is T and so the compiler can deduce the second ...
