Re: [Dev-C++] #DEFINE versus cont variables in array inicializations

[<a_g...@ya...>]

Hi Andre,
you are right, there's probably no third way out. Now I prefer to use the first one due to two reasons.
1> Being textual subsitution, the #define macro does not use up memory size whereas an integer uses up 32 bytes, though that is negligent for most purposes.
2> The more important being that apart from compiler systems that support C++ along with C, the interpretation of const by the compilers around is a bit non-standard. Like in the Cygwin gcc complier assigment to const variables result only in a warning at compile time and program runs fine, and prints out 20!!!.
#include <stdio.h>
int main()
{
   const int i = 10;
   i=20;
   printf("%d\n",i);
   return 0;
}/*main*/
So well although I cannot remember of a third way to do it right now, obviously the first approach is better.

Dear Users,

For the sake of flexibility, I think we only have two ways to iniciatize
a
size of an array:
1) via #define:
#define MAX 10
...
int vect[MAX];
...

2) via cont variable:
const int size=10;
...
int vetc[size];
...

So, in both ways, everytime if I need to change the size of the arrays, it´s
only necessary to change 10 to the other value.

-->My questions:
1) Is there more ways to to this?
2) For theese two ways presented here, when use one and when use the other?
Explaining a little more what I need to know: in a "good programming
technique"
point of view, what of theese two is the preferred of the programmers
(please
don´t answer "pointers" ...lol).

Regards
André
