If a program is in several source files,the best arrangement is to place each definition 
in some relevant source(.c) file, with an external declaration of function n variables in
 a seperate header file that is included by #include at the front of each source file..

RE: What's the best way to declare and define global variables

Best Way to represent a variable as global is Just define the variable at the initial or just below the headers files

For Example:-
#include<stdio.h>
#include<conio.h>
#define PIE 3.1415

void main()
{
body of program

}
getch()

where PIE is define globally.
