Do not ask user for input (i.e asking user to enter number of processes) . Please use C++ (First Come First Served)
Each process will include at least: a list of CPU bursts (possibly in an array alone or combined with I/O times) a list of I/O times ( possibly in an array) a current CPU burst and a current I/O time variables to store the response time, waiting time, and turnaround time
During execution each process will be in one of 3 states: Ready (accumulating wait time) Executing (using current CPU time) Blocking (using current I/O time)
