[RESOLVED] Delete Vector Error

Hello to all, i have dynamic allocate memory for a vector but when i delete it i get an run time exception error.



Thanks.

Maybe you could be more especific... Show your code, for example.

Code:

---


#include <vector>

using namespace std;

int main()
{
        vector<int>* obj = new vector<int>[5];
        delete obj;
        return 0;
}

---

I've done this before, and I did it like this:

Code:

---

std::vector<int>* obj[5];
for (int i = 0; i < 5; i++)
    obj[i] = new std::vector<int>;

---

Then to delete them, you would do this:

Code:

---

for (int i = 0; i < 5; i++)
    delete obj[i];

---

Just out of curiousity, when would you want to use dynamic vector allocation?

Vectors are a VERY lightweight storage class.

You are using new[], but then using delete instead of delete[]. Frankly, I agree with Sharsnik: just write:

Code:

---

#include <vector>

using namespace std;

int main()
{
    vector<int> obj[5];
    // ...
    return 0;
}

---

or:

Code:

---

#include <vector>
#include <tr1/array> // Or #include whatever is appropriate.

using namespace std;

int main()
{
    tr1::array<vector<int>, 5> obj;
    // ...
    return 0;
}

What a stupid mistake ?
