STL Vector problems

[Franz]

I have two questions

1.How can I append a vector to the other vector?

2.

std::vector<int*> myvector;

int *pNum = new int;
*pNum = 4;
myvector.push_back(pNum);

*pNum = new int;
*pNum = 3;
myvector.push_back(pNum);

Now, I want to sort myvector. Therefore, the sequence will become 3, 4. I want to use stl sort function. How can I use that?

Any replies will be appreciated
