printing vector elements error message

I'm a beginner in c++. The following simple program to push elements into vector and to display them while traversing, is not working correctly. Compiler says "Expression:vector iterator is not derrencable." Can any one help me about this ?? #include <iostream> #include<vector> int main() { int n; std::vector<int>x; std::vector<int>::iterator it; for (it = x.begin(); it != x.end(); ++it) { std::cout << "enter an element in the vector:" << "n"; std::cin >> n; x.push_back(n); std::cout << "vector:" << "n"; std::cout << *it; } return 0; }
