    string

    I know that I can use string instead of char when declaring a char or an array

    So here is a function prototype written in c

    void decrypt(const char in[],char out[]);

    can I re-write it in c++ like this:

    void decrypt(const string in[], string out[]);

    No. It would be:

    void decrypt(const string in, string out);


    ...since a single string is an array of chars...
    Code:
    bool flip(bool value)
    {
        return std::pow(std::exp(1), std::complex<float>(0, 1) 
        * std::complex<float>(std::atan(1)*(1 << (value + 2))))
        .real() < 0;
    }

    Well you would want to pass out by reference.

    Code:
    void decrypt(const string in, string &out);

    heh, that's what I meant
    Code:
    bool flip(bool value)
    {
        return std::pow(std::exp(1), std::complex<float>(0, 1) 
        * std::complex<float>(std::atan(1)*(1 << (value + 2))))
        .real() < 0;
    }
