    retrieving the entire string after using getline

    I am using the getline command for the user to input a name to allow for spaces. however when I later try to print out the name if i enter a name with spaces it does not output correctly. How can i print out all the data that was gathered by the getline command.

    Code:
    //FILE: ola3.cc
    //AUTHOR: Written by Cory Smith
    //INSTRUCTOR: Dr. J. Yoo
    //COURSE: CSCI 1170-06
    //DUE DATE: 10/2/2003
    //DESCRIPTION: This programs prompts that prints a statement for each overnight guest at its hotel. 
    //             It inputs informations from the user and saves it to a file. This information is then recalled from this location and printed on the screen
    //INPUTS: Name, room number, room rate, number of nights, telephone charges, and other charges
    //OUTPUTS: Name, room number, room rate, number of nights, telephone charges, other charges, tax, subtotal, total
    //CONSTANT: taxRate = .0925 which stands for 9.25%
    //FORMULAS:  tax = roomCost * taxRate;
    //           subTotal = roomCost + tax;
    //           total = subTotal + telephoneCharges + otherCharges;

    Six years overdue huh. And it's still worth points?

    Anyway, I thought you said you were using getline to read in the name:
    Code:
    inData >> guestName;

    o whoops haha that needs to be changed but anyways

    Code:
      cout << "Guest's name: ";                               //The guest's name
        getline(cin, guestName);
        outData << guestName << endl;
    That is the getline im talking about. So it saves whatever I enter to a file.

    But when i try to retrieve it from a file it only works in what was enter was a name without spaces such as simply Cory, while Cory J. Smith would not work.

    Code:
    inData >> guestName;
    That is how i am recalling it from the file that it was saved to previously.

    Sorry if this doesnt make sense but essentially i need it to be able to accept a name with spaces.

    Whether your assignment was due in 2003 or 2009 on October 2nd, it's still late.

    Anyways, let's assume you write each name on a separate line. All you'd need to do is this:

    PHP Code:
    getline(someStreamsomeString'\n');

    The string is not multiple names it's on name.

    getline(cin, guestName);

    if i enter Cory J. Smith then Cory J. Smith is saved to the file.

    later when i do inData >> guestName;

    it reads it as

    Cory
    J.
    Smith

    three separate lines

    I need a way to grab it all from the txt file as one line.

    if I just enter Cory it works just fine.

    Exactly my point. If you don't use getline here too, it doesn't make a single bit of difference what you did the first time.

    So when I am recalling it from the file I need to use getline also?

    getline(inData, guestName);
