Can I return Vector from Virtual Function

Expand Post »

Hi,

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

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?

Re: Can I return Vector from Virtual Function

misspellings mostly

C++ Syntax (Toggle Plain Text)
class A
{
public:
virtual vector<int> getSomeStuff();
private:
};
 
 
vector<int> A::getSomeStuff()
{
    vector<int> ay;
return ay;
}
 
int main()
{
}
class A
{
public:
virtual vector<int> getSomeStuff();
private:
};


vector<int> A::getSomeStuff()
{
    vector<int> ay;
return ay;
}

int main()
{
}

Re: Can I return Vector from Virtual Function

I prefer

C++ Syntax (Toggle Plain Text)
void  A::getSomeStuff(vector<int> & vec)
{
  ...
}
void  A::getSomeStuff(vector<int> & vec)
{
  ...
}

to avoid a possible copy on return.
