    INT ARRAY Permutation!

    Hi everyone

    I'm ultra newb.

    I looked through this board for permutation of numbers but everyone wanted permutation of characters and those seemed to be the example..

    I REALLY need some sample code to work on that can give me permutations of an int array, in my case 1-9. I would LOVE if someone could help me come up with an algorithm to do this or a way. I really don't want to use the STD or next_permutation, SIMPLE CODE please, that doesn't require memory allocation, or pointers. Nested loops, and recursive functions would be nice.

    THANKYOU VERY MUCH (in advance)

    ARTHUR

    Post YOU ARE SOOOOO(!!!!!!) WELCOME!!!!!

    Now show some effort!
    Code:
    bool fun(bool value)
    {
        return std::pow(std::exp(1), std::complex<float>(0, 1) 
        * std::complex<float>(std::atan(1)*(1 << (value + 2))))
        .real() > 0;
    }

    At least try starting it yourself, and when you are stuck just post what you have here.
