Basic steps for Linux system--c Language Program development (basic steps including GCC)

1, use VI or VIM to write program files

2. Use GCC to translate all source files into computer-aware format (compilation)

3. Use the./a.out executable file as command execution

Working steps for the GCC compiler:

1. Handle all pre-processing instructions

2, the first step of the processing structure translated into computer-recognized format (compilation)

3. Merge the results of the second part into the final executable file (link)

GCC options:

-E only handles all preprocessor directives

-C only completes preprocessing and compilation (no links are compiled)

The processing result is a target file with an. o as the extension

-O is used to determine the name of the resulting file to be compiled.

-std=c89/-std=c99

Used to decide to compile with that version of the specification

The C89 specification is used by default
