I/O Sentences

[dsladev]

Im new at C++ and am trying to teach myself. I want to ask the user of the program why they are feeling a certain way, but not do anything with the sentece. So its like
-how are you feeling?-
user -good-
-why are you feeling good?-
user- blah blah blah-
-ok i understand now-

[William Hemsworth]

Well, unless you're going to add some artificial intelligence to this, simply put a load of predetermined questions / answers in and apply them to an if / switch statement.

[dsladev]

i need to know the commands... i got the program all situated.. i just need to know what to do with that one sentence... i have if/while/switch and all that in there..

Post the code. We can't comment on what we can't see.

[dsladev]

keep in mind i just started :(, so its probably going to look retarded to most of you.. i wanted to see if i could create a program that would talk to me.. i would like to add more questions, just not yet..
the problem is (well the one i see) is that if the person types in more than one word for the reason, the program wont work..

im new at programming and advice is well appreciated
thanks for the website on system("pause")

Dear,

You must have to use bb code tags to format your source code. Read How to use bb code tag?.

[VernonDozier]

Yes, code tags and indentation/formatting. See previous link and below:

[code=cplusplus] // code here

Here's your code. Much easier to read.

the problem is (well the one i see) is that if the person types in more than one word for the reason, the program wont work..

Not 100% sure what you mean. Are you worried about something like this?

Enter an integer: 2 3
Enter another integer:

Second question skipped due to the fact that there was an extra response to the first? Is that what you're talking about?

[dsladev]

thanks.. sorry for before
i dont understand why getline wont work for my compiler.. i tried to use that as well and it just skipped over the command..

It's not that getline isn't working, it's that you're using cin & then using getline, what is happening is the \n delimiter used in cin, for example when you put that you're feeling good, you press enter, at that point \n is in the buffer.

When you use getline after cin then it reads the \n that is still in the buffer & skips it, that is what is happening here, to sort the problem, clear the input buffer with cin.ignore();

Alternatively, there is also a thread on the input buffer along with clearing it right here.

[dsladev]

thanks everyone.. i know it wasnt that hard of a program probably for you that have been doing this, but it was difficult for me, and i appreciate everone's help.. here is the finished one (well the revised one).. test it out plz :-).. tell me what you think, be honest..
i might be stupid because it took me till 3 am to get the program completely working but i learned a lot of extra information that i can add to future programs :-D.. and now im going to go crash into my bed... thanks again
