I have a question about converting from std::vector to an array.
I have a vector of pointers to object. How can I convert it to an array of pointer to objects in C++?

The vector is
std::vector<pin*> *_PINS

I want to convert it to
pin** pins_arr

I’ve tried everything that has been suggested in here but it doesn’t work

I guess the reason why it’s not working is because I have pointer to object as a type instead of basic type.

Would you please help me with this? I’ve been stucked for the whole morning.

Thank you,

    Edit: if you really insist on doing a conversion like this, I suppose you could do something on this order:

    std::vector<PIN *> *_PINS;

_PINS = new std::vector<PIN *>;

// make life a little easier:
std::vector<PIN *> tmp = *_PINS;

PIN *pins = new PIN *[10];

for (int i=0; i<10; i++)
    pins[i] = tmp[i];

PIN **ppins = &pins;

    I have to agree with Ed.S though — what you’re doing here defeats most of the purpose of using std::vector in the first place, and frankly strikes me as a bit silly.
