How to write faster?

Question

C++ / C#

int summ = 0;
foreach (int r in new int[] { 5, -6, 2, 7, -5, 9, 1, -3 }) summ += (r < 0) ? r : 0;

how to write this expression in a simpler way (at a low level), for a lecturer who loves "everything is simple".

Answer 1

Maybe so? Outline for readability

int summ = 0;
int[] massive = new int[] {5, -6, 2, 7, -5, 9, 1, -3};
foreach (int r in massive)
{
  if (r < 0)
  {
    summ += r;
  }
}

Either use Linq

int summ = (new int[] {5, -6, 2, 7, -5, 9, 1, -3}).Where(x => x < 0).Sum();

Answer 2

int result = new int[] { 5, -6, 2, 7, -5, 9, 1, -3 }.Where(i => i<0).Sum();

Answer 3

foreach (int r in new int[] { -6, -5, -3 }) summ += r;

or
or I did not understand what the lecturer wants.

Answer 4

What is there to simplify? The code itself is basically illogical. If this array is created in a loop (read, by a weak link) with previously known values, which are then simply added up by a trigger, then what's the point?
What an inadequate lecturer you have.
