University Course Registration System

Concurrent course registration simulation in C using POSIX threads.

Build

make

Run demo

./course_registration

The default run demonstrates:

• 10 concurrent student threads
• CS101 = 2 seats, CS102 = 1 seat, CS103 = 3 seats
• at least 3 high-priority students
• visible contention and priority-based ordering

Design notes

• Each course has its own mutex/condition variable.
• Student requests are queued per course and processed by priority first, then arrival order.
• One thread is created per registration request.
• Seat counts are updated only while holding the course mutex.
