In computer science, an object file is an organized collection of separate, named sequences of machine code.
It is poor programming practice resulting in undefined behaviour. Files should never store memory addresses (real or virtual), since there's no guarantee a valid object will always reside at the same location in memory, unless the programmer can be absolutely certain the object will outlive the file (such as when referring to active objects in memory via a temporary file).To embed an object in a file, the object must be stored in an independent file. The file in which the object is embedded simply links to the object's file. In this way, whenever the object is updated (and saved), all files in which it is embedded will also be updated.
why does a program consists of more than one object file in c++

The Java.io.File class is an abstract representation of file and directory pathnames. Following are the important points about File:Instances may or may not denote an actual file-system object such as a file or a directory. If it does denote such an object then that object resides in a partition. A partition is an operating system-specific portion of storage for a file system.A file system may implement restrictions to certain operations on the actual file-system object, such as reading, writing, and executing. These restrictions are collectively known as access permissions.Instances of the File class are immutable; that is, once created, the abstract pathname represented by a File object will never change.

Because a linked object is created and stored in a separate source file and then it is linked to the destination file, while an embedded object is created in a separate source file but then it is inserted into the destination file , becoming the part of that file.

difference between a form file and a form.
a linked object
Both are binary files but the differences between those are:- 1) we can execute an executable file while we cannot execute an object file. 2) An object file is a file where compiler has not yet linked to the libraries, so you get an object file just before linking to the libraries, so still some of the symbols or function definitions are not yet resolved which are actually present in the libraries, and that's why we cannot execute it. Once an object file is linked with the library by the compiler, then all the symbols are resolved and we get an executable file which can be executed on the appropriate platform. So basically the difference is that we get an object file when we don't link with library while executable file is with the linking phase. In gcc we can direct compiler not to link with library and so it will prepare the object file :- gcc -c test.c It will automatically create test.o object file when you try to execute it like:- ./test.o cannot execute binary file
embedded object
A pathname is the location of a file or object in the context of a file system. A URL is the location of a file or object in the context of an internet web server.
