hello,
i had an error when compiling my program.
i declared Lq as array:

IloNumArray Lq(env);
.
.
.
and i used it as shown:
for(q= 1; q <= N ; q++)<br />  {
  for(l=1; l<= Lq[q].getsize(); l++)<br /> {
.....

i get this error:
[color=red]erreur: request for member 'getsize' in 'Lq. IloNumArray::operator[](q)', which is of non-class type 'double'[/color]

i understood that "getsize" can't be used in this context..
someone have an idea???


Thanks

Lq[q] returns an IloNum (you can see it as a double).
If you want to know the size of Lq, you should use Lq.getSize()

But from your code, it seems that you want a 2 dimension array, not a 1 dimension one. If this is the case, you might consider using an IloArray<IloNumArray>

Hi,
Thank you for replying Sir...
i declare Lq as two dimensional array as you told me...
IloArray<IloNumArray>

but another error occured:

[color=red]'getsize' : is not a member of 'IloArray<class IloNumArray>'[/color]

what shall i do??

Thank you.

Don't you miss the upper case 'S' ?

I replaced "s" by " S" but the problem still occured..
i changed the definition of my array..i declare it IloIntArray ( because i found that .getsize is a member of IloIntArray and not of IloNumVar..)

this error occured:
[color=red]left of '.GetSize' must have class/struct/union type.[/color]

what that mean???
