stl vector with data being pointers to structs

[monkeyking]

Hey,
Is it possible to have a vector with pointers to structs like



struct datPoint{
int x;
int y;
int z;
int date;
double **data
}

and then something like



vector<*datPoints> vv;

but this gives me an error that looks like.



runRelate.cpp: In function ‘std::vector<iArray, std::allocator<iArray> > getTestIndividuals(const char*)’:
runRelate.cpp:325: error: no matching function for call to ‘std::vector<iArray, std::allocator<iArray> >::push_back(iArray*&)’
/usr/include/c++/4.2/bits/stl_vector.h:597: note: candidates are: void std::vector<_Tp, _Alloc>::push_back(const _Tp&) [with _Tp = iArray, _Alloc = std::allocator<iArray>]

thanks in advance

It compiles fine for me:


#include <vector>

struct datPoint
{
int x;
int y;
int z;
int date;
double **data;
};

int main()
{
std::vector<datPoint*> vv;
}

Perhaps the * was simply on the wrong side?

Unless you were asking something else...

It's been a while since I've worked in C++, but from what I remember, you'd want to change it to something like...



typedef struct _datPoint{
int x;
int y;
int z;
int date;
double **data
} datPoint;




vector<datPoint*> vv;


I added the typedef because, iirc, if you don't do that then you'd need to fully qualify "struct datPoint" every time you referenced it.

I changed the location of * in the vector declaration because that's my understanding of how a pointer is declared, although there are a lot of weird options available...

Only in C.

Thanks again.
