Analyse C programming

For this you are required to review the program code Additionally, you are required to assess the code complexity by determining McCabe and Halstead metric values. Also you are to outline a test plan in pseudo code or program code if preferred, that would provide as close as possible to 100% path coverage. Finally you are to devise an N-version programming test strategy for the function skip_eol.
The assignment does not require any new programming but does require the critical analysis of the given program code.
