This is a compliler for a simple C language named after C1 below (which is a simple form of real C and does not contain the pointer, struct and multi-dimension array features).

bison and flex should be installed

$ sudo apt install bison
$ sudo apt install flex

MUST BE RUNNED UNDER LINUX OS Environment

There are two source files in this project, which are named as C1.y and C1.lex and placed in the "config" directory and four source files, named as ast.c,error.c,list.c and symtab.c, placed in the "src" directory.

And after make there will be three more source files -- c1c.lex.cc, c1c.tab.h and c1c.tab.c and they are lexical analyzer and syntax analyzer. Also there will be one executable file named c1c, which can analyze programme written in C1 language, create AST and then translate the source code into AT&T assembly language that can be lded and executed under Ubuntu OS.

This project includes the following files and directories:

README.md	this file
makefile	a makefile to build c1c.lex.cc, c1c.tab.h, c1c.tab.c and c1c
config		directory storing C1.y and C1.lex
src			directory storing source files
include		directory storing header files
doc			directory storing documents
test		directory storing three test files
bin			directory storing execution/objective files
	--run	a shell script for automatically making and running

NOTE: YOU CAN JUST RUN "run" IN DIRECTORY CALLED "bin" INSTEAD OF FOLLOWING THE GUIDE BELOW AND THE PROGRAM WILL AUTOMATICALLY TESTS THE FILE IN THE DIRECTORY NAMED "test".

# Enter: ./
make

# Enter: ./
bin/c1c "infilename" # infilename means file written in C1 language

or

bin.c1c -o "outfilename" "infilename" # outputfile means file to be stored for results.if not existing, it will be created)

And then you can use as and ld(run as with --32 and ld with -melf_i386 if your OS is 64-bit Ubuntu) to create an executable file and then execute it.
