Semaphore Program in C || Process Synchronization

In this lecture on semaphore program in C, you will learn how to use a semaphore variable to avoid race condition and solve process synchronization problems.

A semaphore variable is an integer variable that can be initialized and modified by two atomic operations: wait and signal. Semaphores help to achieve process synchronization. Semaphore variable can also be used to avoid race condition. To use semaphore variables you must understand two things:
1. The theory of semaphore variable - https://dextutor.com/semaphores-for-process-synchronization/
2. How to create threads - https://youtu.be/Ga9uegju0EQ
