Post-increment within a self-assignment

Question

I understand the differences between i++ and ++i, but I\'m not quite sure why I\'m getting the results below:

static void Main(string[] args)
{
    int c = 4         


        

Answer 1

The expression on the right-hand-side of an assignment is evaluated completely, then the assignment is performed.

   c = c++;

Is the same as

   // Right hand side is calculated first.
   _tmp = c;
   c = c + 1;

   // Then the assignment is performed
   c = _tmp;
