    Your question isn't really clear. As far as scanning for a newline, just loop through the array until you encounter '\n'. Just be sure that the array wasn't read from the stream in binary mode, or else things will get more complex.
    #include <cmath>
    #include <complex>
    bool euler_flip(bool value)
        return std::pow
            std::complex<float>(0, 1) 
            * std::complex<float>(std::atan(1.0)
            *(1 << (value + 2)))
        ).real() < 0;

    If you're reading input with %s, then you're never going to get a \n in any buffer.
    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.
