	 Purpose: This function checks its first argument for its type according   to the second parameter passed to the function .
			HERE type checking is for number , string , or alphaNumberic String.
			-if we  have to check for number then second parametr will have a string of all digits(0-9).
			- if check is for only string then II arg is a string of all alphabets in upper as well as lower case.
			- if check is for alphanumeric string then II arg is a string of all alphabets as well digits.
