WebJul 28, 2024 · Improve this question. My goal is to write a CPU Scheduling Simulator in C++ using the STL features as far as possible. So far, I have only written the code for FCFS and have not provided any input method. What sticks out most to me is the definition of the process class. The way I have designed the program, there is very poor encapsulation. WebProgram Explanation. 1. Initialize two array pid [] and bt [] of size 15. 2. Ask the user for number of processes n. 3. Ask the user for process id and burst time for all n processes and store them into pid [] and bt [] respectively. 4. Calculate waiting time of each process by the formula wt [i] = wt [i-1] + bt [i-1].
