    I shouldn't do this, but
    Code:
    ...
    int inum;
    char*word=new char[16];
    float fnum;
    
    ...
    
    cin>>inum>>word>>fnum;
    
    ...
    edit: that wont work the way you want it... look at the New York part...

    Here's some code:
    Code:
    #include <iostream>
    int main()
    {
        std::cout << "Depends on what the delimiters are.  It looks "
                     "like they are all spaces, so I'd read in a line "
                     "at a time, then take the first and last token "
                     "and store them as ZONEID and PRICE.  Whatever "
                     "is left in the middle would be the ZONEDESC.";
        std::cout << std::endl;
    }

    This is off topic, but I think mine works fine. Also, you don't need the return 0; according to the standard, even though VC++ 6.0 warns you if you don't put it.

    Point well taken, but I didn't know what else to call him that would've been appropriate.

    As far as I see it there is no discussion...what the standard says is final

    I know them not: not therefore am I short
    Of knowing what I ought."
