how to get iterator to a particular position of a vector

Question

Suppose i have a

std::vector v
//and ...
for(int i =0;i<100;++i) 
 v.push_back(i);

now i want an iterator to, let\'s say 10t

Answer 1

This will work with any random-access iterator, such as one from vector or deque:

std::vector::iterator iter = v.begin() + 10;

If you want a solution that will work for any type of iterator, use next:

std::vector::iterator iter = std::next(v.begin(), 10);

Or if you're not on a C++11 implementation, advance:

std::vector::iterator iter = v.begin();
std::advance(iter, 10);
