14.10.1.Computing sum with template arrays for double array

#include <iostream>

#include <vector>

using std::cout;

using std::endl;

using std::vector;



template <typename Array>

double vectorSum(Array a, long count) { // Array can be a pointer or an iterator

  double sum = 0.0;

  for (long i = 0; i<count; ++i)

    sum += a[i];

  return sum;

}



int main() {

  double temperature[] = { 10.5, 20.0, 8.5 };



  cout << "array vectorSum = "

       << vectorSum(temperature, sizeof temperature/sizeof temperature[0])

       << endl;



  return 0;

}
