RE: Catch The Error
|
Actually there is no sytactical error in this code. It just that the if condition always evaluates to false 'coz the query returns the day of the week with trailing spaces(except for Wednesday) and thus will never be equal to 'Tuesday'. So, the output will be :
On Tuesday : Today is Tuesday
On other days :
Today is Wednesday
The output 'Aloha!!! Today Is Tuesday' is never displayed. |
