10.3. Simple code layout method

The simplest method of using template code is to include both the declaration and definition of the template in every compilation unit that uses instances of the template. From a code layout point of view, this is very easy, since the template declaration and definition can be kept in a single header file. Using the stack example, the code in Example 10-1 on page 379 and Example 10-2 on page 380 would be combined into a single header file, for example, stack.h, which is then included by every compilation unit that wishes to use the template. Alternatively, the header file for a template declaration can include the source file that contains the template definition. Using the stack template example, the header file, ...
