What is the major difference between a vector and a stack?

Question

Both act like a stack. Both have push and pop operations.

Is the difference in some memory layouts?

Answer 1

I think the main difference is that vector is a range based container. It can be easily used thanks to its member functions such as begin and end. Vector can be easily initiated with {} form. We can use new features of modern C++ like range-based loops.

vector vec{ 7, 3, 1, 9, 5 };
for ( auto &i : vec ) {
    std::cout << i << std::endl;
}

Whereas it is not possible for std::stack.
