What are the permissions of (ass1.c, ass1, and CIT497A) at each stage of the following command:?

1. umask 027
2. ./ass1 > CIT497A/ass1
3. cc -o ass1 ass1.c
4. vi assl.c
5. chmod 640 ass1.c
6. umask 027

   after this all files created by your username will have the default permition that looks like this " rwxr-x—"

   vi assl.c

   >rwxr-x— assl.c

   chmod 640 ass1.c

   >rw-r—– ass1.c

   chmod og+w ass1.c

   >-rw-rw–w- ass1.c

   cc -o ass1 ass1.c

   >rwxr-x— ass1

   chmod a+x ass1

   >-rwxrwx-wx ass1

   umask 077
   mkdir CIT497A

   > drwx—— CIT497A

   ./ass1 > CIT497A/ass1

   > -rwx—— CIT497A/ass1

   there you go.
