problem with rand()
 

Hi Everybody
I am using rand function in my solver and somehow I need random numbers between 0 and 6 but the problem is that when I simply use rand() function, I get unexpected huge numbers and these numbers are constant run by run.
I have read somewhere in forum that rand(an integer) should work.but in my case I have error.
can anyone help me with this?
thanks in advance

rand() returns an int, so you need to normalize by RAND_MAX and convert to float/double if necessary. And if you don't use srand() to seed the PRNG, you will always get the same sequence.
