That's my code. I need to know how, at the very beginning, how to fix the fact that for every character that is "invalid" it repeats...

Invalid input.

Go ahead and compile it if it doesn't make sense. Thanks in advance.

Use ignore with no arguments, which will default to skipping 1 '\n' (you don't want the space like you have it)

It still does it. When i enter just random gibberish it still displays multiple "invalid inputs"

Is there something about the sticky post at the top of the forum titled Read me: How do I flush the input stream? that you don't understand?

[jonsca]

Use a construct like this

cin.ignore ( std::numeric_limits<std::streamsize>::max(), '\n' );

(see the sticky thread on flushing the input stream for more details).

This will ignore a number of characters up until the maximum capacity of the buffer or until it hits a newline.

Since ans is a character, when you enter "adfsffef<enter>" the 'a' is written into ans and all the rest of it stays in the stream, so the loop executes once for each character and the newline.

yeah i can't get it to work. It's not flushing the stream, i only need the stream to accept the first value the user inputs, and i don't know how to that.

Thanks for explaining it, i read the flushing the stream post and didn't get it.

This implies you tried changing your code. But since you didn't post the new code, we can't explain what you did wrong.

Okay, i'll keep that in mind, but jonsca helped me figure it out. Thanks for the help. =)
