            try
            {
                j.phone = int.Parse(Console.ReadLine());
                Console.WriteLine("phone number of user is:" + j.phone);
            }
            catch (Exception e)
            {
                Console.WriteLine(e.Message);

I was a bit confused by this too... if you don't assign i to j the program runs just fine so I don't really understand why the compiler wants to enforce this. That said, it does, so we just have to deal with it.

The easiest way to solve your problem is to initialize j with a new statement. Alternatively, you can use the default statement.

jeetu j = default(jeetu);
jeetu i;
...
i = j;

In .NET, you must instanciate structs the same way as classes I believe, with the new keyword.
jeetu j = new jeetu();
