This is misleading in that "void main()" would also be a bad idea- can cause the application to crash in some runtime environments.  Best to use int main(int argc, char **argv) instead.

The register modifier hints to the compiler that the variable will be heavily used and should be kept in the CPU’s registers, if possible, so that it can be accessed faster. 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...

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].
