C++ difference between delete and destroy?
490941
Delete (when used with a pointer) destroys what the pointer points to (e.g., pointer is still there, and can point to something else).  Destroy destroys the pointer/object itself.\n\nFor instance:\n\nchar** charArrayPtr = new char[50];\ndelete charArrayPtr;\ncharArrayPtr = NULL;\ncharArrayPtr = new char[25];\n\nBut if you did\n\ndestroy(charArrayPtr);\n\nyou couldn't use charArrayPtr anymore.\n\nReally, no real need to call destroy explicitly, for the most part.

When u Delete a file from CD it is not Deleted Physically so each time you delete a file you reduce the capacity of the RW/DVD. So It's depend of the Size of the File that u Delete and Times you do it.

DROP is a DDL...\n\n\n\nDELETE is a DML.

delete a person? \nAgainst the law surely?

when you delete a file, it actually removes the directory info so it appears not to exist, it is still on the disk however until the physical space it is on is overwritten with new data

-> is the in-place dereference operator. It is most commonly used in OOP.\n\n$a->{'b'} is exactly the same as $$a{'b'}\n\n-> can also be used for 'method' calls with blessed objects.\n$a->function(); is exactly the same as module::function($a);\n\nAn 'object' is Perl is actually just a reference to a variable, usually a hash (associative array). As such, whenever you want to use an object, you have to dereference it (othewise perl doesn't know what to do).\n\nSee the following in perldoc:\nhttp://perldoc.perl.org/perlop.html - Perl operators\nhttp://perldoc.perl.org/perlref.html - Perl references\nhttp://perldoc.perl.org/perlobj.html - Perl objects\nhttp://perldoc.perl.org/perlmod.html - Perl modules

I think it depends on what you are trying to delete . When this happens to me I just right click then delete.

I'll put a bit of more information than the previous two answers.. or it'll seem like I'm answering for 2 points ;-)\n\nA for loop in C++ basically has the syntax:\n\nfor([initializations];[condition check];[updates])\n{\n  //statement1;\n  //statement2;\n}\n\nInitializations: Initialize counters, iterators.. any data to be set or reset before the loop starts executing. Multiple initialization statements can be provided in a comma-separated-list.\n\nCondition Check: While the condition is true, keep iterating through the loop. Dont make this a list.\n\nUpdates: Update iterators, indices, counters etc. which need to be updated with every iteration of the loop. Again this can be a comma-separated-list.

Control+break ... It works good.. depends of the programs it can stop fast... it´s like End task in windows

yes in c++\nno side effects

This folder may be used by installation/setup programs (and other programs) to store temporary data in temporary files. If you wish to delete the files in this folder, do so when not installing any software on your computer. It might be best to restart your computer prior to deleting any files in the folder.If a file in this folder is in use and has been locked by the program using it, you will not be able to delete it (you will be shown an error message), but some programs do not lock their temporary files and may crash if you delete the temporary files they are using.

Varies based upon if the suspected info is on your home computer or a larger computer, say at a bank.\n\nPeople "delete" files or emails.  But "delete" is like tearing the Table of Contents out of a book.  It does not remove the chapter.  Some utility programs can rebuild the Table of Contents.\n\nYou can deleted/erase a email - but the person you sent it to may have a copy, your home computer or the company's network computer may keep a copy - and the computer network operation support people - usually keep a copy for at least 12 months.\n\nEven "erasing" a file - which normally is something like writing "binary 0's" over the data - in some cases, does not fully erase the info.\n\nIt really varies based upon the computer, what software might have been used - and what you are looking for.\n\n(Personal info:  Computer Security Officer for state's dept of Corrections for 10 years)

consider ...\n\nstruct test\n{\nint x;\nint y;\nstruct test next_t;\n};\n\nhow big would it be? it would try to go on forever - it's a recurring structure\n\nnow consider\n\nstruct test\n{\nint x;\nint y;\nstruct test *pnext_t;\n};\n\nmuch better - the definition 'stops' at *pt which needs to be assigned a value (pointer to a struct test) so only growing as required.\n\nso, you can next structures as long as there is no self referencing structure causing a referencing loop - and you can nest pointers to structures - which is usually the best way to proceed

Whoa!  Bad things!\n\nThe superuser has ultimate power over the system, and therefore has complete control of the system, including the ability to completely demolish the filesystem.\n\nThe root of the UNIX filesystems is denoted by a single dot (".")\n\nIf a program with appropriate permissions executes the unlink (effectively a delete) command, it will remove the pointer to the root inode, and hence the entire filesystem will be lost.  Granted, the data will still be there but useless now.
