Vectors within Structures

[joraara]

Hi,

I appreciate if someone is able to help me.

I've declared a structure and two of it's members are vectors, let's say:

#include <vector>
using namespace std;
struct str{
vector< int >v1();
vector< int >v2();
} str;

However, I don't manage to use those vectors as usual, for example: str.v1[i]=n or str.v2.resize(j).

Is there any way to handle them throughout the program?

Any help would be wellcome. Thanks.

Remove the parenthesis from the vector declarations and it should work. Whenever you want to declare an object with no arguments, leave off the parenthesis. Otherwise, the compiler thinks you are declaring a function.

Thanks ilikepython for your reply.
I've just done what you said and the compiler detedcs no error.
Now the problem is trying to build the .obj; it's showing 3 errors and I have no idea what they mean. Here is the message:

Linking...
Facturacion.obj : error LNK2001: unresolved external symbol "struct product * producto" (?producto@@3PAUproduct@@A)
Facturacion.obj : error LNK2001: unresolved external symbol "struct factur * factura" (?factura@@3PAUfactur@@A)
Debug/Facturacion.exe : fatal error LNK1120: 2 unresolved externals
Error executing link.exe.

What should I review?
Thanks.

That probably means the compiler can't find the definition of something. Can you post the Facturacion.cpp code?
