deleting objects

Hello,

I've declared the following class:

Code:

---

class person
{
public:
        int age;
        char *name;

        person(char *p_name, int p_age);
        ~person() {
                delete[] name;
        }
};

---

In my main program I've declared an array of persons. At the end of my program I'm deleting those objects as following:

Code:

---

for(i = 0; i < 10; i++) delete persons[i];

---

Somehow I'm getting the following error:
DAMAGE: after Normal block (#43) at 0x00431AF0.
I'm getting the same error when I'm deleting the name of a person by

Code:

---

delete name;

---

(without the [])

Can someone tell me what the error means, how I can avoid it and how I can delete the names in the object destructor? (Maybe it isn't necessary at all, but it seems to me, since I'm using a pointer.)

are you sure name isn't a wild pointer? for each delete you should have a new.

In the class constructor, set name to NULL. Then, in the destructor, check to see if name == NULL. If its not, delete it. you may also get the DAMAGE: warning if you attempt to write out of bounds of your allocation:

Code:

---

char* n = NULL;
n = new char[10];
n[10] = NULL;
...
delete [] name;

---

On the delete, you will get that warning. Check any string modifications that you do to make sure that you dont write out of bounds.

Z.

The constructor is defined like this:

Code:

---

person::person(char *p_name, int p_age): age(p_age)
{
        int len;

        len = strlen(p_name);
        name = new char[len];
        strcpy(name, p_name);
}

---

I think it's allright.
Do I actually have to delete strings in the destructor of a class, or are they cleared automatically?

a) are the persons allocated dynamically (with new)

b) why don't you use the string class?

c) why don't you use vector or list ;)
