Re: Templates specialization

I am trying to write a function to count the number of occurances of a
particular element in an array. I am also trying to specialize the
function for strings. I am passing the array as reference to the
function. Is there a way I can avoid hardcoding the size of the
array? I know we can do it if we pass the array as a pointer but can
we do it for pass by reference?

#include <iostream>
#include <string>
using std::cout;
using std::string;

template<typename T, int len>
int my_count(T (&arr)[len], T ele)
{
    int count = 0;
    cout << "LEN = " << len << std::endl;
    for(int i=0; i< len; ++i)
    {
        if(arr[i] == ele)
            ++count;
    }
    return count;
}
