Execution flow of C program

There are various steps of the execution of the C program that is given below. The following step of the execution

  1. Write source codes
  2. Preprocess
  3. Compile
  4. Link edit
  5. Load
  6. Execute

Editor or IDE: This is the first step while writing the source codes of the program, there must require any editor or IDE (like notepad and notepad++ etc) where we can write own source code and save it by using source codes (.c) and headers ( .h). Preprocessor: In this section, the source code includes the file and replaces the symbols and send to the next section compiler. Compiler: In this section, the compiler compiles the source code of the program and creates the object codes (.obj and .o)and sends to the linker. Linker: In this section, the linker links the object codes into static libraries (.dll and .so) and creates the executable code (.exe). Loader: In this section, the loader loads the executable code by using shared libraries (.dll and .so)file and send to the CPU for execution according to user input and return output.
