gcc demo.c -o demo # compile
./demo             # execute
111                # show result
                   # change the demo.c
gcc demo.c -o demo # compile
./demo             # execute

gcc demo.c -o demo # compile
./demo             # execute
333                # show result
  
...  

now

cmon demo.c        # compile and execute it
111 
                   # change the demo.c
222                # show result
                   # change the demo.c
333                # show result

1. The gcc need to be available on your machine.
2. This tool just support gcc compiler no other compilers like clang.
3. It just supports compiling a single c file.
4. It doesn't support passing command-line arguments
