    Question cin / scanf

    Hi,

    Can somebody please help me out?

    Consider the following snippet:

    cout << "Enter your name: ";
    cin >> n;

    cout << "Hello " << n << "!" << endl;

    If I input 'Joe Bloggs' it will only print out 'Hello Joe!'.

    When using cin or scanf to read a string, how do you make it read everything the user types in (including spaces)?

    Thanks in advance.

    use cin.getline()
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    using:

    cin.getline>> name;

    will assign all the strings on the line till it finds a new line character.

    cin.get(givenName).get(familyName);
    would be usefull if only two names, but u can add more to it.

    yeah, the cin >> syntax's fields are delimited by spaces or endlines.
