Arrays & 2nd file.cpp

I need to make four or five arrays for my program. I would like to place them in another file as to not cluter up my main program, how can I accomplish this? Also, if I create my arrays in another file will that file aslo need #include<iostream> & a main function? I just tried it and I left the file pretty much blank except for my array which looks like this:

Code:
char *Array1={"one", "two", "three"};


But I'M getting the following error:

In file included from ArrayTestCase.cpp:3:0:
Arrays.h:4:45: error: scalar object ‘Array1’ requires one element in initializer

char*Array1[]={"one", "two", "three"};

"one" is a pointer to character.
"two" is a pointer to character.
"three" is a pointer to character.
{"one","two","three"} are several pointers to character.

char* is a pointer character.

char*Array1[] is space for an (memory limited) infinite number of pointers to character. Except that you nicely chose to use only 3.


How can I tell? Operator precedence.
[] evaluates before *.

Thus you could parenthesize as

char(*(Array1[]))

Array1 can be indexed, has fixed size (determined by the initializer list), and is accessed as an array. On access c gets a value of the type outside those parentheses.
Array1[0] is a pointer to character.
