Homework Answers
The algorithm for the given code is:
Step 1: Start
Step 2: Declare variables process[20], priority[20],
arrival_time[20], burst_time[20], turnaround_time[20],
waiting_time[20], i, j, limit, sum = 0, position, temp,
average_wait_time, average_turnaround_time.
Step 3: Display Enter Total Number of Processes
Step 4: Read the variable limit.
Step 5: Display Enter Burst Time and Priority For
Processes
Step 6: for i = 0 To limit-1
Step 6.1: Display Process i + 1
Step 6.2: Display Process Burst Time
Step 6.3: Read variable burst_time[i]
Step 6.4: Display Process Priority
Step 6.5: Read variable priority[i]
Step 6.6: process[i] = i + 1
Step 7.: for i = 0 To limit-1
Step 7.1: position = i
Step 7.2: for j = i + 1 To limit-1
Step 7.2.1: if priority[j] <
priority[position]
Step 7.2.1.0:
position = j;
Step 7.3: temp = priority[i]
Step 7.4: priority[i] = priority[position]
Step 7.5: priority[position] = temp
Step 7.6: temp = burst_time[i]
Step 7.7: burst_time[i] = burst_time[position]
Step 7.8: burst_time[position] = temp
Step 7.9: temp = process[i]
Step 7.10: process[i] = process[position]
Step 7.11: process[position] = temp
Step 8: waiting_time[0] = 0
Step 9: for i = 1 To limit-1
Step 9.1: waiting_time[i] = 0
Step 9.2: for j = 0 To i-1
Step 9.2.1: waiting_time[i] =
waiting_time[i] + burst_time[j]
Step 9.3: sum = sum + waiting_time[i]
Step 10: average_wait_time = sum / limit
Step 11: sum = 0
Step 12: Display Process ID Burst Time Waiting Time Turnaround
Time
Step 13: for i = 0 To limit -1
Step 13.1: turnaround_time[i] = burst_time[i] +
waiting_time[i]
Step 13.2: sum = sum + turnaround_time[i]
Step 13.3: Display process[i], burst_time[i],
waiting_time[i], turnaround_time[i]
Step 14: average_turnaround_time = sum / limit
Step 15: Display average_wait_time
Step 16: Display average_turnaround_time
Step 17: Stop
