why this one is not legal identifier

Hi Chinna,

Legal identifiers must be composed of only Unicode characters,
numbers, currency symbols, and connecting characters (like underscores).

In int e#;
You are including # which does not come under above characters..So its not legal.

Also, please note that identifiers may not begin with a digit. But digits are allowed as the second or subsequent characters. This is primarily to avoid conflicts with numeric literals (e.g. 1L or 1.0f).
