2.4. Overloading Function Templates

Like ordinary functions, function templates can be overloaded. That is, you can have different function definitions with the same function name so that when that name is used in a function call, a C++ compiler must decide which one of the various candidates to call. The rules for this decision may become rather complicated, even without templates. In this section we discuss overloading when templates are involved. If you are not familiar with the basic rules of overloading without templates, please look at Appendix B, where we provide a reasonably detailed survey of the overload resolution rules.

The following short program illustrates overloading a function template:
