Dynamic Array

[fantasma]

Greetings from Portugal to everyone.

I'm building a project to a course in my university and i've stucked in some compiling error given by NetBeans and g++ in my dynamic array implementation. Glad if someone could give a hand to this.

Here is the code

#pragma once

#include <iostream>
#include <string>

#include "Edificio.h"
#include "Camiao.h"

using namespace std;

class Armazem:public Edificio
{
private:
    Camiao **vecCamiao[];
    int numCam, tamCam;
public:
    Armazem();
    Armazem(int c, string d);
    Armazem(const Armazem &a);
    virtual ~Armazem();
    /*Armazem& operator =(const Armazem& p_arm);
    bool operator ==(const Armazem& p_arm) const;
    bool operator >(const Armazem& p_arm) const;
    void escrever(ostream& out) const;*/
    void insereCamiao(Camiao *vC);
    void listaCamiao(Camiao *vc);
};
Armazem::Armazem(){}

Armazem::Armazem(int c, string d):Edificio(c,d)
{

   tamCam = 50;
   numCam = 0;
   vecCamiao = new Camiao*[tamCam];


}
Armazem::~Armazem(){}
void Armazem::insereCamiao(Camiao* vC)

{
    if(numCam == tamCam)
    {
        Camiao ** nVec = new Camiao*[2*tamCam];
        tamCam = tamCam*2;
        for(int i=0;i<numCam;i++)
        {
            nVec[i]=vecCamiao[i];
            vecCamiao = nVec;
            vecCamiao[i]=vC->clone();
            numCam++;
        }
    }
}
void Armazem::listaCamiao(Camiao* vC)
{
    for(int i=0; i<numCam; i++)
    {
        cout<<vecCamiao[i];
    }
}

And the error code:

Thank you in advance for your time responding to this tread.

It appears your trying to create a 2-dimensional array. The problem is, a pointer for a 2-Dimensional array has 2-levels of indirection, but you are attempting to create a pointer with 3-levels of indirection.

Try taking the [Square Braces] off your declaration of vecCamiao...

Olá

It might help if we knew what

Camiao **vecCamiao[];

Was...

Thanks for your replies.

Fbody, thank you. It was my fault since I never looked at that declaration with its due attention. That surely did the trick ;)

Gerard, that declaration was the error, but I was trying to create a dynamic array of pointers to pointers.

Thank you both, once again
