How C++ is executed?

editer(source code) -> source file --(compiler)--> object file ---(linker)--> execute file ---> RUN

source code : high level language

what compiler's do ?

- preprocess : #define variables save , ignores comments

- compile : preprocessed code to assembly code 

- assembler : assembly code to binary code (= machine code that hardware can understand)

what linker's do?

- link library and object file

- execute file created !
