I guess the subscript here in the sense of arrays:Subscript is the offset of the array. Say, int array[5];To access the second element, we use array[1], where 1 is the subscript.Which mean to point to the location after 1  such element. So it will pass array[0] and it will point the array[1].

There are several restrictions on the use of the register modifier. First, the variable must be of a type that can be held in the CPU’s register. This usually means a single value of a size less than or equal to the size of an...
