User will enter the date of birth in the form of dd//mm//yy form and after subtracting today's dd//mm//yy from usre's date of birth (dd//mm///yy) console display his/her age.

I have written code but problem is-what is method for displaying today's date in the dd//mm//yy form and have to finding the difference?


Answer
Well there are a couple of ways to tackle this. You could have the user enter the day, the month, and the year into three seperate inputs, and then form the string yourself (this is the most user friendly/secure way). You could use a combination of the Substr() function of the String class to check to see if each two digit number is followed by a /. You will want to check out the DateTime object and perhaps use that to subtract the date, and then output it using DateTime.Format(); The information is available here; http://msdn.microsoft.com/en-us/library/8kb3ddd4.aspx
