Thanks
I guess that I will have a special function checkvaraibles to check the
varaibles and arrays(I can disable the function by compiler flag)
In order to check an array I will have in checkvaraibles something like this for
every array:
for (i=-8;i<0;i++)
if (info[i]!=-1)
{
printf("mistake in the board");
printf(" %d ",i);
}
for (i=0;i<64;i++)
if (info[i]!=22)
{
printf("mistake in the board");
printf(" %d ",i);
}
for (i=64;i<72;i++)
if (info[i]!=-1)
{
printf("mistake in the board");
printf(" %d ",i);
}
Note that info[i] when i=-8 is not a mistake because I used the following
definitions
int PADDED_info[80];
int * const info = PADDED_info+8;
