I kinda have to put my previous C questions on hold cause this one is more important now... I have already coded the insert and delete functions on my binary search tree but the delete function is incomplete. There's a couple of things I need help in... 1) Is my insert function good or can it be improved somehow? 2) My delete function...
I have an class (A) which uses a heap memory allocation for one of it's fields. Class A is instantiated and stored as a pointer field in another class (B). When I'm done with object B, I call delete, which I assume calls the destructor... But does this call the destructor in class A as well? Edit: From the answers, I take that (pleas...
In my C++ main function, for example, if I had a pointer to a variable which uses heap memory (as opposed to stack memory) - is this automatically deallocated after my application exits? I would assume so. Even so, is it good practice to always delete heap allocations even if you think they will never be used in a situation where the me...
I want to delete several specific values from a matrix (if they exist). It is highly probable that there are multiple copies of the values in the matrix. For example, consider an N-by-2 matrix intersections. If the pairs of values [a b] and [c d] exist as rows in that matrix, I want to delete them. Let's say I want to delete rows like ...
The user id on your connection string is not a variable and is different from the user id (can be GUID for example) of your program. How do you audit log deletes if your connection string's user id is static? [EDIT] The best place to log insert/update/delete is through triggers. But with static connection string, it's hard to log wh...
Hi, I was creating external dependecies in one of my repos. I made a mistake and I want to delete one of these dependecies. I can't delete the folder because that deletes the folder from the parent project. I'm using tortoise svn-client and I can't find a command to achieve this, I removed the external property from the properties list...
So I know this is a common question but there just doesn't seem to be any good answers for it. I have a bucket with gobs (I have no clue how many) number of files in them. They are all within 2k a piece. 1) How do I figure out how many of these files I have WITHOUT listing them? I've used the s3cmd.rb, aws/s3, and jets3t stuff and t...
Alright, I think we all agree that what happens with the following code is undefined, depending on what is passed void deleteForMe(int* pointer) { delete[] pointer; } The pointer could be all sorts of different things, and so performing an unconditional delete[] on it is undefined. However, let's assume that we are indeed passing...
I always wondered why automatic setting of the pointer to NULL after delete is not part of the standard. If this gets taken care then many of the crashes due to invalid pointer would not occur. But having said that I could think of couple of reasons why standard would have restricted this: 1. Performance: An additional instruction co...
Can anyone here help me out with a script that will let me, when run, delete all the folders and their contents in whatever folder it is placed in. ...
Duplicate of: Is there a reason to call delete in C++ when a program is exiting anyway? I think we all understand the necessity of delete when reassigning a dynamically-allocated pointer in order to prevent memory leaks. However, I'm curious, to what extent does the C++ mandate the usage of delete? For example, take the following progra...

Say, I have two tables Courses and faculty_courses - each has a primary key course_ID that is varchar(50) not null. I am trying to delete a row from the Courses table - so assume have to delete that row from both tables since they are linked by a relationship. I wrote this - doesn't work - says Incorrect syntax near the keyword 'JOIN'...
I have spent a lot of time recently reading the HTTP 1.1 specification and relating it to REST. I have found that there are two interpretations of the HTTP DELETE method in regards to its "idempotency" and safety. Here are the two camps: If you delete a resource with HTTP DELETE, and it succeeds (200 OK), and then you try to delete tha...
I'm a bit confused with JavaScript's delete operator. Take the following piece of code: var obj = { helloText: "Hello World!" }; var foo = obj; delete obj; After this piece of code has been executed, obj is null, but foo still refers to an object exactly like obj. I'm guessing this object is the same object that foo pointed to. ...
Instead of deleting records in my Django application, I want to just mark them as "deleted" and have them hidden from my active queries. My main reason to do this is to give the user an undelete option in case they accidentally delete a record (these records may also be needed for certain backend audit tracking.) There are a lot of for...
