. // what i can do int this area
}


the output looks like this


1.	Find Student Data
2.	Add New Student Data
3.	Delete Student Data
4.	Stop and Print the Report

Enter your option : 1  //or 2 or 3 or 4

What is the point of i++ on line 39? I don't think the var i does anything, unless I completely missed something.

Also I would do it with returning int, but maybe I am just old fashioned :)

Then you can just tell them to input the option, then return it after checking validity if needed.

you might get a problem with your while look on line 35 as your i variable isn't declared anywhere i can find.
