Should I be getting this error : variable-sized object may not be initialized?

Yes. The error is expected: VLAs (variable length arrays) can't be initialized.

But real problem seems to be that you want thisBucketCount number of buckets which is not what this code does:


You probably want to allocate thisBucketCount number of bucket objects. So you need do:

 bucketP thisBucketArray =
malloc(thisBucketCount * sizeof(struct bucket));

 if (thisBucketArray == 0) 
 /*handle error */

 for (i = 0 ; i < thisBucketCount ; i++)
    thisBucketArray[i].collisionCount = 0;
    thisBucketArray[i].firstKey = 0x00;

Notice that I have removed the cast. casting the result of malloc() is error-prone and dangerous.

You should also check if malloc() failed by checking if it returns NULL.

"Error 91: Object variable or With block variable not set" in code running perfectly last Friday
That is because rCategory is Nothing. The .Find is not returning anything. To test it, change your code to this. For iCategory = 1 To UBound(vCategories) Set rCategory = rPatterns.Find(What:=vCategories(iCategory)) If rCategory Is Nothing Then MsgBox vCategories(iCategory) & " Not Found" Else .Points(iCategory).Format.Fill.ForeColor.RGB = rCategory.Interior.Color

How to test if a variable exists and has been initialized
Use Parameter expansion: : ${var:?} Remove the colon if the empty string is a valid value (i.e. you only want to test for definedness). : ${var?} If you don't want the script to stop on the problem, you can use if [[ ${var:+1} ]] ; then # OK... else echo Variable empty or not defined. >&2 fi

Clearly there is no such column named 'task'. Please confirm your column name at the following line. task=c.getString(c.getColumnIndex("task")); Confirm your column name and you are good to go.

Error in Swift class: Property not initialized at super.init call - How to initialize properties which need use of self in their initializer parameter
You just have to invert the order super.init/properties in your initializer: required init(coder aDecoder: NSCoder) { self.datasourceOfflineVideos = ASDataSource(tableViewController: self) self.datasourceOnlineVideos = ASDataSource(tableViewController: self) super.init(coder: aDecoder) } instance properties comes first, then the superclass initializer can be invoked. But that's n
