========================================================

How do I validate the name to be a character, the bet to be integer and validating user input for Y for yes and N for no. Please help anyone?

What do you mean?

ctype::scan_is() can test if an array of characters is alphabetic.
http://www.cplusplus.com/reference/locale/ctype/scan_is/

PLEASE USE CODE TAGS (the <> formatting button) when posting code.
It makes it easier to read your code and also easier to respond to your post.

Hint: You can edit your post, highlight your code and press the <> formatting button.

I would like to do a validation on characters for entering player's name. But I do not know how to go round about doing it..

I provided you with a link on how to do it.
That page includes an example.

If you don't want to use scan_is, you can always use isalpha().
