Question

The trick is in that I don’t know the size of the string yet. I need to be able to ask user for a word, and that this word would be stored in a vector.

int main()
{

    vector<char> word (80);

    // get the word from user
    for(int i=0 ; getchar() != '\n' ; i++)
        {
            cin >> word[i];
        }
    // print the word from user
    for(int i=0 ; i<=word.size() ; i++)
        {
            cout << word[i] << endl;
        }


    return 0;
}

EDIT: It’s simply that I want to capture a word input from keyboard, any word at all, a string of characters, etc. Example: Let’s say I want to add the word “obvious” to a vector, so that I can later manipulate the vector. So I type “obvious”, then press enter, and there you go, I have a vector of size 7 with the word ‘obvious’ in it.

Answer 1

std::string str;

// I'm confused about whether you want a line, or a word.
// this gets a line
std::getline(std::cin, str);

// this gets a word
// std::cin >> str;

vector<char> word(str.begin(), str.end());
