    returning a string from a function

    howdy
    i'm trying to figure iut how to return a string from a function. have i missed something in the following code???

    ----------code---------------



    #include <iostream>
    #include <string>
    using namespace std;

    string stringy ()
    {
    string string1;
    cout<<"Enter a string"<<endl;
    getline(cin, string1);
    return string1;
    }


    int main ()
    {
    int number;
    string string1;

    stringy();
    cout<<"How many times?\n";
    cin>> number;

    for (int index = 0; index < number; index++)
    {

    cout<<index <<">--->>>"<< string1 <<"<<<--<"<< index<<endl;
    }
    return 0;
    }


    i wrote this in emacs and am running rh 2.4.7?
    it seems to compile allright but when run it will not place the entered string (string1) into the line between the index numbers.

    thanks from a sel teaching newbie

    Looks like a simple case of ignoring return result

    Try
    string1 = stringy();

    Howdy Salem,
    Very Cool.
    this return thing is a bit confusing. next it will pointers and adresses.

    Thanks

    I'll give an advice. If you write a function that returns a value, no matter what kind of value is, you should NEVER use this function to print any text out on the screen. It's not healty for your program.
    Current projects:
    1) User Interface Development Kit (C++)
    2) HTML SDK (C++)
    3) Classes (C++)
    4) INI Editor (Delphi)

    Howdy GaPe,

    do i understand you to say this piece -
    cout<<"Enter a string"<<endl; - would go in main or somewhere else.

    YES, in the main or into some other function that returns nothing.
