Prettier syntax for "pointer to last element", std::vector?

Question

I'm wondering if there is prettier syntax for this to get a normal pointer (not an iterator) to the last element in a C++ vector

std::vector<int> vec;

int* ptrToLastOne = &(*(vec.end() - 1)) ;

// the other way I could see was
int* ptrToLastOne2 = &vec[ vec.size()-1 ] ;

But these are both not very nice looking!

Answer 1

int* ptrToLastOne = &vec.back(); // precondition: !vec.empty()

Answer 2

int* ptrToLast = &(vec.back()); // Assuming the vector is not empty.
