delete an array

[seetono]

I have a struct like this:

    class ClassOps{
        
        public:
        Array *array2[100];
        };

Say i want to delete the whole array

       for ( int g=0; g<5; g++){
        delete [] array2;
        array2= NULL;
        }

Is there a way to remove an array entirely? Seems to have problem with that

Of course it has a problem with that. You may only delete what has been new'd. Is there some reason you though you needed to try the delete 5 times?

Sure. Allow the ClassOps object to expire.

You can not delete the array because you did not allocate it in the heap. You can delete elements of the array of type Array * if they were allocated in the heap. It can be done for example the following way

for ( int i = 0; i < 100; i++ ) delete array2[i];

If i follow with this code, the application will hang....

You let it go out of scope.
