Block Diagram of Execution of ‘C’ program


























The compilation and execution process of C can be divided in to multiple steps:
  • Preprocessing - Using a Preprocessor program to convert C source code in expanded source code. "#includes" and "#defines" statements will be processed and replaced actually source codes in this step.
  • Compilation - Using a Compiler program to convert C expanded source to assembly source code.
  • Assembly - Using a Assembler program to convert assembly source code to object code.
  • Linking - Using a Linker program to convert object code to executable code. Multiple units of object codes are linked to together in this step.
  • Loading - Using a Loader program to load the executable code into CPU for execution.

    Hi Vivekananda, this is really a clear diagram for Block Diagram of C Program execution.

    Thanks, Merient Infotech
