    getline overload, solution didn't work

    I had this problem last night. (http://www.cprogramming.com/cboard/s...threadid=12648).

    But what worked then, doesn't seem to work now: on the 2nd cin it skips the getline and propts for "make". Sorssen (I think) suggested input.ignore() to skip the '/n' in the buffer, but it's not working now.

    I'll attach the whole prog if that helps, thanks in advance

    Code:
    istream& operator>>(istream& input, cars& c)
    {
    	cout<<"Make ";
    	input.getline(c.make,10);
    	cout<<"model ";
    	input.getline(c.model,10);
    	cout<<"capacity ";
    	input>>c.cpcty;
    	cout<<"price ";
    	input>>c.price;
    	input.ignore();
    	return(input);
    };
    
    ostream& operator<<(ostream& oput, cars& c)
    
    //....
    
    main()
    {
    	cars car1;
    	cars car2;
    	cars car3;
    	cars car4;
    
    	cin>>car1;
    	cin>>car2;
    	cin>>car3;
    	cin>>car4;
    	cout<<car1;
    	cout<<car2;
    	cout<<car3;
    	cout<<car4;
    	return (0);
    }

    Worked fine here. Shouldn't it prompt for "make" first as that's the first element? What are your inputs?

    Thanks for the help!

    When you say it works fine, how far did you get. There are four inputs, char, char, int, double? It's the second cars record that messes up?

    Entered four complete records and got four complete records as output. From stdout -

    Code:
    Make 1
    model 1
    capacity 1
    price 1
    Make 2
    model 2
    capacity 2
    price 2
    Make 3
    model 3
    capacity 3
    price 3
    Make 4
    model 4
    capacity 4
    price 4
    1       1       1       1
    2       2       2       2
    3       3       3       3
    4       4       4       4

    I ran the prog again, just to see. It work fine. I did 9 more times and it failed once more. 8 out of 10. Are compliers funny like this, or am I seeing things. I'm useing bcc55.

    No, it's normally the programmers. You said in your previous post that the inputs were char, char, int, double. Your struct contains char, char, int, int. The problem may be here. What inputs are causing it to fail?

    Well, it ran through car1 fine. At car2 it promts for both make and model on the same line (it did this just twice out of nearly 20 now), then go through the rest of the cars vars (car3, car4) the same as car two. I'm chalking it up to the smurf in my computer now, because I can't get it to happen again. Thanks for you help Sorensen (your fist name isn't Jessica, is it?).

    No. My second name isn't Sorensen either.
