c++ windows programming?

Question

Hi this is in C++ using Borland....i have an error "Constant expression required" on this line : "TableType aTable[x];"...it seem that the number from "edit->text" is not valid...Can somebody tell me why it wont take the value of "edit->text"?

x=edit->Text.ToIntDef(0);

TableType aTable[x];

aTable[x].tableNo= MyRest.findTable(edtNo->Text.ToIntDef(0));
aTable[x].computerType = (edtname->Text.ToIntDef(0));
aTable[x].name = GuestName->Text;
aTable[x].arrivalTime = Arrival->Text;
aTable[x].departTime = Departure->Text;

Tables has already been give a size of [40] somewhere in the program..

Answer 1

the compiler needs to know the size of the aTable array so it can allocate the memory for it. If you give it fixed size it will work, something like:
TableType aTable[50];
Another option is to malloc().
