Re: [Dev-C++] dynamic array

[<ste...@ge...>]

Try this;

read some entry and then something like; (change the type of variable so =
it's suitable for the entries.)

entry_var =3D new int[size_of_entry];
if(!entry_var)
{
    cout << "Unable to allocate memory!";
    getch();
    exit(-1);
}

do your stuff with the entries, and then remember to delete it like =
this;

delete(entry_var);
