This linking is accomplished by placing the name of a shareable library in the executable image. The declaration extern int foo void is performing exactly the same function as the header file of a library. It is created from object files, but it's certainly not an object file itself. The Netherlands faces a shortage of developers. The header file contains the function declarations, global variable declarations, as well as preprocessor directives needed for the library. Instead of linking same object again and again into the library, each module share information of a object with other module having same object. There is more chances of error and failure chances. Linker are also called link editors.

When we compile Any program in Linux using “gcc” for example ” gcc -o helloworld helloworld.c” it creates an executable with “helloworld” name in single. The preprocessor handles “#include” “#define” “#ifdef” and so forth.
In theory, it outputs a 'clean' C++ source module - without any. A C source file goes through two main stages, (1) the preprocessor stage where the C source code is processed by the preprocessor utility.
This time the loader comes into action, it loads the binary code into memory for execution.
The file does not have to be C source code because the preprocessor is doing text manipulation. Improved By : ArnaMaity.

What is the function of the preprocessor, compiler, loader, and linker in C++ Quora
Linker is a computer program that links and merges various object files together in order to make an executable file. Update Cancel. It takes as input a file that contains text usually C source code that may contain preprocessor directives and outputs a modified version of the file by applying any directives found to the text input to generate a text output.
The only systems I know that have both a linker and a loader are mainframes… since I know IBM mainframes, I will use them as an example. Hi Jim, thanks for response.
