Why are my random numbers always the same?
fortran, gfortran, random
Solution
The random number generator produces pseudo-random numbers. To get different numbers each run, you need to initialise the random seed at the start of your program. This picks a different starting position in the pseudo-random stream.
Problem
I'm using the `random_number` subroutine from Fortran, but in different runs of program the number which is being produced doesn't change. What should I include in my code so every time I compile and run the program the numbers change?
