c++ - what does size of array and size of its pointer means? -

Recently, I read the code jerk and it confuses

  fixed string const Dirs [6] = {"-n", "-ne", "-se", "-s", "-sw", "-nw"}; Int a = sizeof (dirs) / sizeof (* dirs);   
 And the size of an array is equal to 6, which is 6.  
 So my question is:  
 
 
 What does the shape show (DIR)? What is the size of the total array?   
 
 What do you represent (Dears) of size?     
  
  represents the size size    
 Thus, sizeof (* dirs) * number of elements = sizeof (dirs), because the number of elements * the size of each element is the size of the whole array  
 Thus, the number of elements = size ( DIR) / size (* Diaz).
