c++ - how to code an explicit specialization for a function template (bubble sorting array of strings ) -

to begin , pretty new c++ . have code function template explicit specialization sort array of integers, , array of strings .

my main program

#include <iostream> #include "sort.h"  int main() {     int a[] = { 1234, 546, 786, 2341 };     char* c[6] = { "harry", "jane", "anne", "john" };      sort(a, 4);     sort(c, 4);      (int = 0; < 4; i++)         std::cout << a[i] << std::endl;     std::cout << std::endl;      (int = 0; < 4; i++)         std::cout << c[i] << std::endl;     std::cout << std::endl; } 

sort.h file ( file containing template )

template<typename t, typename t1> void sort(t* items,  t1 count) {     t1 t;      (int = 1; a<count; a++)     (int b = count - 1; b >= a; b--)     if (items[b - 1] > items[b]) {         t = items[b - 1];         items[b - 1] = items[b];         items[b] = t;     } } 

problem here : says : "error c2912: explicit specialization 'void sort(char *,int)' not specialization of function template" getting confused " char * c[] " , how make specialization type .

 template<>     void sort<char ** >(char** p, int count)         {           } 

you have match primary template signature exactly, e.g. so:

template <> void sort<char *, int>(char ** p, int count) {     // ... } 

so t = char * , t1 = int.
