17. Comment on an array of the void data type.
    

1. 1. It acquires the data type with the highest precision in it

   
   
   

   2. It can store any data-type

   
   
   

   3. You cannot have an array of void data type

   
   
   

   4. It only stores element of similar data type to first element

   
   
   

   5. None of these
