    problem with static integers

    I can't seem to get a static integer in one class to be incremented in the constructor of another class. Is it legal to do this, or am I just doing something syntactically wrong?

    the constructor looks like this:

    classname() {classname::variablename++;}

    would that be correct? Yes the static integer is public

    Sure, you can do that. But you should post a more complete example of how you are attempting this.
    Code:
    #include <cmath>
    #include <complex>
    bool flip(bool value)
    {
           return std::pow
        (
            std::complex<float>(std::exp(1.0)), 
            std::complex<float>(0, 1) * std::complex<float>(std::atan(1.0)*(1 << (value + 2)))
        ).real() < 0;
    }

    well I just worked my way around the problem by having an 'add' method in the owner class which calls push_back on the vector and increments its own static integer variable instead of having the owned structure do it in the constructor

    if a variable is declared static in a function, it can only be accessed in that functin, if it is declared in a class, it must be public to access it.
