Printing out vector<string> char by char

I have learned a bit of C in university and I'm now learning C++ independently. I'm trying to print out std::vector char by char. I know, that in C, strings are arrays and are terminated by '\0' terminator. Can I assume the same thing in c++? I use C++14.

This works, but I'm unsure if it's the correct way to do this. I know, I can use getline(std::cin, line) to read from stream as well. Which one is more preferred? How would you make my code better?

using namespace std;

int main()
{
    cout  str;
    for (string temp; cin >> temp; ) {
        str.push_back(temp);
        // If input ends with enter, break loop
        if (cin.peek() == '\n') break;
    }
    cout ::iterator it;
    for (it = str.begin(); it != str.end(); ++it) {
        cout  '\0 terminated? */
        for (size_t i = 0; (*it)[i] != '\0' ; ++i) {
            cout << (*it)[i];
        }
    cout << ' ';    
    ++it;   
    }
    cout << "\n\n";
}

So the first thing you can do is to use container loops

for (std::string &mystring : str) {
// do someting
}

The second thing would be to have a look at rbegin() and rend, which give you reverse_iterators.

You can find a very good reference here: http://www.cplusplus.com/reference/string/string/rend/

Together you would get something like that

for (std::string &mystring : str) {
    for (std::string::reverse_iterator rit=mystring.rbegin(); rit!=mystring.rend(); ++rit) {
        std::cout << *rit;
    }
}
