Macro in C

[andrug]

Hello Everybody,

I have a problem.
if I have an array of (for example) 50 elements, but i need to write from element numer 100 to 149

I wanted to define a macro:
the code I wrote is (in the same file):

static array[50]
 
#define  array[a]   array[(a)- 100]
 
 
void main()
{
      array[101] = 5;
}
 

but it doesn't work.
Can you please help me?

Thank a lot!!!!!

#define  array[a]   array[(a)- 100]
 

It wouldn't you have the syntax of your macro definition wrong, a function like macro is defined using parentheses ( and ) so you macro would need to be defined something like

#define  ARRAY(a)   array[(a)- 100]

just update the code in the folloing manner,
static int array[40];
#define array(x) array[(x)-100]
void main()
{ array[130]=7;
}
I THINK IT WILL BE WORK FINE;
