Solution

The process of forming an executable file from C source code involves several steps:

  1. Preprocessing: This is the first step in converting C source code into an executable file. The preprocessor takes the source code as input and processes include files, conditional compilation instructions and macros. The output of this step is an expanded source code.

  2. Compilation: The expanded source code from the preprocessing step is then compiled. The compiler checks the code for syntax errors and converts it into assembly code.

  3. Assembly: The assembly code generated by the compiler is then converted into machine code by the assembler. The output of this step is an object file containing machine code.

  4. Linking: The final step is linking. The linker takes one or more object files and combines them into a single executable file. It also links any external libraries that the program may need to run.

So, the correct sequence is: Preprocessing, Compilation, Assembly, and Linking.

C-Facts: The core part of Linux operating system was completely developed in C language.The instructions (called the source code) written in C are saved in a file with .c extension. For eg: Calculator.c. This is the source file.There is a special program called compiler, which is used to compile the source file. Once compiled, an object file with extension .obj is created.There is yet another program called linker, which combines one or more object files to create a single executable file. The executable file can have any extension. For example, files in Windows usually have .exe extension.
