Showing that std::acuumulate is just as good as a for loop on

accumulate_array_example.cpp

#include <numeric>
#include <iterator>
int vals[5] = {1, 2, 3, 4, 5};

int main()
{ 
    // Force the array into a const (just because I don't want to iterate on modifiable cells
  	auto const & b = vals;
    
  	int sum = std::accumulate(std::begin(b), std::end(b), 0);
  
    return sum;
}
