Jesus, really a great video, I was searching for this action when the user puts a char or string instead of int and how to clear and "reset" cin. It was a big help!

Thanks, man.
U've really help me.
I came across these functions in c++(and I use them also) but I really don't understand the principle on which they operate. Your video has been so helpful to me.

Thanks.

Waiting for more

Thanks man, you a lifesaver. It took a while for me to incorporate this to my code but I got there in the end. Cheers.

Bruh thanks for making this I was wondering why I had to input the number twice before It would accept anything
Then realized I was asking for the input twice

How would you use this to validate a character string length?
For example, the user needs to input a 6 letter word. If he inputs only 5, display an error message.

Thank you for the super video. It was very simple and I was struggling with this for a while. Question - how could test whether it is a number and whether it is a specific number like 2 or 4?
