Defining a Function Template Specialization

When we specialize a function template, we must supply arguments for every template parameter in the original template. To indicate that we are specializing a template, we use the keyword template followed by an empty pair of angle brackets (< >). The empty brackets indicate that arguments will be supplied for all the template parameters of the original template:

// special version of compare to handle pointers to character arraystemplate <>int compare(const char* const &p1, const char* const &p2){    return strcmp(p1, p2);}

The hard part in understanding this specialization is the function parameter types. When we define a specialization, the function parameter type(s) must match the corresponding ...
