A file mode describes how a file is to be used, to read, to write to append etc. When you associate a stream with a file, either by initializing a file stream object with a file name or by using open() method, you can provide a second argument specifying the file mode.
e.g. stream_object.open("filename",filemode);
Following is the list of filemodes available in C++

When you close a file what happens to the undo history list for that file?
When you close a file, the undo history list for that file is typically cleared or reset. This means that any changes made during the session are no longer available for undoing once the file is reopened.

What is the internal process when a file is deleted from hard disc?
When a file is deleted from a hard disk, the operating system deletes the file's entry from the directory and it releases the space occupied by the file back to the pool of available free space. Most of the time, the actual contents of the file are not erased, but recovering (or undeleting) the file can be difficult because the freed space might be reused for somthing else, and because the information that binds the file's space into meaningful order is lost. The actual process involved depends on the operating system and type of file system. Sometimes, the operating system does not actually delete the file. It can move the file to a list of deleted files, making it available for recovery within a certain period of time or amount of activity. Usually, files in such a "deleted list" are then actually deleted at some later time based on time in the list and space demands on the file system.
