Splet26. mar. 2014 · The shortest job first algorithm runs the process whose burst time is lowest. In the code we are assuming all the processes have arrived already. The burst times are hard coded in the array 'ptime'. As all the processes have arrived and burst times are known they are sorted using 2 'for' loops.
