Answer: Dereferencing a variable that is not a pointer
Explanation:
The execution time also refered to as the CPU time pertaining to a given task is the time that is used by the system to execute a task.
Some of the reasons for a fatal execution-time error include:
• Dereferencing a pointer that has not been initialized properly
• Dereferencing a null pointer
• Dereferencing a pointer that has not been assigned to point to a specific address.
It should be noted that dereferencing a variable that is not a pointer doesn't cause a fatal execution-time error.
GUI is your the method.Hope that helps.
You can do 'ctrl a' to select the whole sheet and then move your cursor to the line in between where it says A and B and you should see it become a black line with arrows moving outwards. Double click when this happens and it should be fixed. :) you can also do this for specific columns by doing the same without highlighting. I hope this helped!! Good Luck!!! :)
