How feasible is this way of generating random numbers ?
I know they are covered in the standard library, but couldn't resist to experiment.
This could be slow due to opening the file, but still have a look....and try to benchmark if it is not obviously flawed.
PS: Taking 5 readings because, somehow in my machine, the first one is mostly coming 0;
int random(int low,int up)
int count = 5;
