代码是:

#include <iostream>
using namespace std;

// compares two objects
template <typename T> void compare(const T&, const T&){
    cout<<"T"<<endl;
};
// compares elements in two sequences
template <class U, class V> void compare(U, U, V){
    cout<<"UV"<<endl;
};
// plain functions to handle C-style character strings
void compare(const char*, const char*){
    cout<<"ordinary"<<endl;
};

int main() {

    cout<<"-------------------------char* --------------------------"<< endl;

    char* c="a";
    char* d="b";
    compare(c,d);

cout<<"------------------------- char [2]---------------------------"<< endl;

    char e[]= "a";
    char f[]="b";
    compare(e,f);

    system("pause");
}

结果是:

------------------------- char*----------------------- ---
