• I reviewed the Contributing Guide.

Describe the bug
In lc_watch.c and lc_action.c, increment and/or decrement operations are being used in the same expressions as other operations which can cause errors and make code less comprehensible/readable.

To Reproduce
Steps to reproduce the behavior:

1. Go to '...'
2. Click on '....'
3. Scroll down to '....'
4. See error

Expected behavior
According to MISRA C:2012 13.3: A full expression containing an increment (++) or decrement (--) operator should have no other potential side effects other than that caused by the increment or decrement operator.

Code snips
If applicable, add references to the software.
