Problem with memory allocation

Meloniasty · #1 01-Mar-2008, 17:02

Hi there, I have some problem with dynamic allocation of two dimensional array. I can manage with base types e.g. int:

CPP / C++ / C Code:

    int**tab;
    tab=new tab* [x];
    for (int i=0; i<x; i++)
    tabl[i]= new int[y];

however when I define my own class:

CPP / C++ / C Code:

     class A{
     //body
}

and try to do as mentioned:

CPP / C++ / C Code:

     A**tab;
     tab=new tab*[x];
     for (int i=0; i<x; i++)
     tab[i]= new A[y];

I receive following error: expected primary-expression before '[' token . I tried to google it, but didnt find proper answer. Could you please enlighten me?

CPP / C++ / C Code:

tab=new tab*[x];

should be

CPP / C++ / C Code:

tab=new A*[x];

Yeah, made mistake while typing message. Unfortunatety this is not the case ;/ But thanks for reply anyway

EDIT:
Noob me, I found the solotiun. Was writing A[i] rather then tab[i]. That's why writing programs during the night is not a good idea ;/ Sorry for mess.
