A demo to show the basic idea of a "Simple C compiler"

On Linux:
make
make run

iron@MSI:/mnt/d/github/Function_me$ make
gcc  -o sc lex.c expr.c error.c decl.c stmt.c main.c emit.c func.c
./sc < demo.c   > demo.s
gcc  -m32 demo.s -o demo

iron@MSI:/mnt/d/github/Function_me$ make run
./demo 2022 11 12 17 35
