    Well your first problem is that you have a main() which is poorly formatted, 100's of lines long AND riddled with goto's.
    Whoever's been responsible for your programming education up to now has been doing a very bad job.

    The whole of each case for series and parallel circuits should be separate functions.

    In both cases, the 2 resistor case is just a special case of the 3 resistor case.
    By suitable initialisation of the 3rd resistor value, you can prune away an awful lot of copy/paste code.

    There are a whole bunch of variables which may be uninitialised.
    Code:
    $ gcc -Wall -Wextra -Wno-unused-result -O2 foo.c
    foo.c: In function ‘main’:

    But because the code is such a rats-nest, there's no point in trying to trace through it all just to check.

    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    You need to learn to:
    * properly indent your code;
    * stop using goto (use while and for instead)
    * use arrays
    * use functions
    * don't flush(stdin)
    The world hangs on a thin thread, and that is the psyche of man. - Carl Jung

    Well, PsychoBandit was polite enough to respond 10 hours ago here : c - I have error in showing the entered Resistor Values at the summary (last part of program) - Stack Overflow

    but haven't seen them here since 13 hours ago so I guess they've solved their problem. Now it just needs to be submitted and marked.
