    could use a little help

    Just wondering if someone could help me with a problem i'm having, i have a class with member functions and a few variables. The program is supposed to do some calculations and then output something specific to the screen depending on what the input was. heres the problem, the only way i can output is by typing the following command in main

    cout << "bluh bluh bluh is" << function() << endl;

    i need to output an entire word but i cant figure out how to return a whole string instead of just a character, i believe it has something to do with pointers if that helps. i have tried to work this out on my own for hours and just cant seem to get anywhere. thanks in advance.

    You can char arrays wich hold entire words, But for beginners (
    are you?) i recommend using the string class, Can't find a
    tutorial right now so:

    Code:
    #include <string>
    
    using namespace std;
    
    string afunction()
    {
    return "hohoho";
    }
    
    int main()
    {
    
    cout << afunction() << endl;
    
    return 0;
    }

    thanks for the response, i tried that and still got an error message. it says something about no operator defined. i think its basically saying that I cant have a function of type string to the right of <<

    some other things i didnt mention before are that the function i am using is a friend function of a class. it takes two arguments of the type of the class. example:
    class example
    ......

    main()
    example ex1, ex2
    cout <<"bluhhhhhhhh is" << function(ex1,ex2)

    my questions are......can i use a string type for a function if its a
    friend function and why might i still be getting that error message

    Problem is simple, Use <iostream> instead of <iostream.h>,
    <iostream.h> is an old version.

    awsome.....works fine now. thanks for your help, it may have been simple but there was no way i was going to find that. that string type will def be coming in handy now.
