I use a table to show the timetable for classes. I found that the constant array has changed when running program.
In the following program. I defined a constant Array time1, and used #table1 to display time1.
#table2 is used to display the modified form. The programming statement is below.
I found that: after I used #table2 to display the revised timetable, click button Display again and time1 has changed. This should not be. Why? Hope to get help.
