        Hello! I am a beginner in C programming and I get a problem with coding
while using gsl_vector_minmax(). It's OK for compiling by GCC 4.6.
However, that will promt "segmentation fault" while executing. In the
GSL handbook, it suggest that the "const gsl_vector" rather than
"gsl_vector", I guess the mistake may cause by this point. However, I
could not construct a "const gsl_vector". In addition, I need some
suggestions on C/C++ programming, can you give me some advices or web
sites? I think I need a BBS which focus on GSL~~ :-)
        My code is follow:
        int main(void)
                int i;
                double *min, *max;
                gsl_vector *w = gsl_vector_alloc(10);
                const gsl_rng_type *T;
                gsl_rng *r;
                T = gsl_rng_default;
                r = gsl_rng_alloc(T);
                for (i = 0; i < 10; i++)
                        gsl_vector_get(w, i) = gsl_ran_ugaussian(r);
                gsl_vector_(w, min, max);
                return 0;
