    Im trying to make a circular buffer in c but I dont know how to go about doing it. Was wondering if anyone could help me out with simple code example or point to any related web site. Have search both this site and google without finding any good help.

    Appreciate any response.

    Why use :
    #define N 10

    could I use :
    const n = 10;

    If I need multiple buffers can I place above code inside struct ? (Is struct similar to class ? )

    btw, thanks for your response

    a struct is similar to a class in as much as it encapsulates the attributes of an object.

    struct car
            char *reg;
            int number_of_wheels;
            int engine_capacity;
    normally behaviour, i.e. functions, is defined outside of the struct as seperate entities.

    In C++, structs and classes are identical save for one trait: by default, all class members are private whereas with structs, public. Thus even structs can have methods(functions). This is why C++ is superior to C.
    #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;
