急!请各位大侠帮忙!!关于模版

[lihh_cn]

设计一个类属函数 max_of_array( ),该函数从一个数组中找出其中的最大原素，数组中存放的元素类型可能是多种多样的。


一定要给出原程序！！！要有输入输出的完整的程序!!!感谢万分!

#include <iostream>
#include <string>
using namespace std;

class ClassA{
//..
public:
　　template <class T>
　　T max_of_array(const T *pArray,const int ArrayCount)
　　{
　　　　T max = (T)pArray[0];
　　　　for(int i=0;i<ArrayCount;i++)
　　　　{
　　　　　　if(max < pArray[i])
　　　　　　　　max = pArray[i];
　　　　}
　　　　return max;
　　}
};


int main(int argc, char* argv[])
{
　　ClassA a;
　　int i[4]={1,2,6,4};
　　double d[6]={3.4,6,4,23.4,5,5.1133};
　　string s[4]={"cc","aa","gg","dd"};

　　cout <<"max of int array: " << a.max_of_array(i,4) << endl;
　　cout <<"max of double array: "<< a.max_of_array(d,6) << endl;
　　cout <<"max of string array: " << a.max_of_array(s,4).c_str() << endl;

　　return 0;
}

there is a function in:

#include <algorithem>
template<class InputIterator>
inline InputIterator max_element(InputIterator first, InputIterator last)

example from MSDN:


#pragma warning(disable: 4786)

#include <iostream>
#include <algorithm>
#include <functional>
#include <vector>
#include <string>

using namespace std;


void main()
{
const int VECTOR_SIZE = 8 ;

// Define a template class vector of int
typedef vector<int > IntVector ;

//Define an iterator for template class vector of strings
typedef IntVector::iterator IntVectorIt ;

IntVector Numbers(VECTOR_SIZE) ;

IntVectorIt start, end, it, location ;

// Initialize vector Numbers
Numbers[0] = 4 ;
Numbers[1] = 10;
Numbers[2] = 10 ;
Numbers[3] = 30 ;
Numbers[4] = 69 ;
Numbers[5] = 70 ;
Numbers[6] = 96 ;
Numbers[7] = 100;

start = Numbers.begin() ; // location of first
// element of Numbers

end = Numbers.end() ; // one past the location
// last element of Numbers

// print content of Numbers
cout << "Numbers { " ;
for(it = start; it != end; it++)
cout << *it << " " ;
cout << " }\n" << endl ;

// return the maximum element in the Numbers
location = max_element(start, end) ;

cout << "The maximum element in Numbers is: "
<< *location << endl ;


int i[4]={1,2,6,4};

int* iloc = max_element(i,i+4);

cout << "The maximum element in Numbers is: "
<< *iloc << endl ;


double d[6]={3.4,6,4,23.4,5,5.1133};
double*dloc = max_element(d,d+6);

cout << "The maximum element in Numbers is: "
<< *dloc << endl ;

string s[4]={"cc","aa","gg","dd"};

string* sloc = max_element(s,s+4);

cout << "The maximum element in Numbers is: "
<< *sloc << endl ;


}
