Can I return Vector from Virtual Function

Jun 24th, 2009

Hi,

I was curious if I could return a vector from a virtual function. I keep getting an error for this.

 Help with Code Tags 
 C++ Syntax (Toggle Plain Text) 
Class A
{
public:
virtual vector<int> getSomeStuff();
private:
}
 
.cpp File
vector<int> A::getsomeStuff()
{
return;
}
Class A
{
public:
virtual vector<int> getSomeStuff();
private:
}

.cpp File
vector<int> A::getsomeStuff()
{
return;
}

Can anyone tell me what I am doing wrong?
