Could someone please let me know how to delete an array that was initialized like this: int array[var1][var2] where var1 and var2 are sizes? If I try to delete it like this:

for(int i=0; i < var2; i++)
       delete [] array[i];
delete [] array;

it doesn't compile. What am I doing wrong? Thanks to whomever replies. edit: fixed your formatting [edited by - SiCrane on April 19, 2004 10:28:29 PM]

The notation you used for declaring your array is for static or stack allocation. In that case, you don''t need to call delete on it.

Thank you for your timely response. So I don''t have to delete it at all? I am extensively testing the program that this is in and I wanted to make sure that it wouldn''t take up any space after I had used it.

Whether or not it takes up space after you''ve used it depends on where you''ve declared it. If it''s a global variable it''s going to take up space throughout the entire program. If it''s a local function variable it will get reclaimed when the function returns.

Nope, you only need to delete when you allocate memory with new. And make sure you know which delete you should be calling, either "delete" or "delete []" for arrays!

Ok, thanks again for clearing that up.
