- Q4. What is race condition?
- Ans.
A race condition is a situation in which the outcome of a program depends on the order of execution of its threads or processes.
Occurs when multiple threads or processes access shared data or resources concurrently
Can lead to unpredictable behavior or bugs in the program
Prevented by using synchronization mechanisms like locks or semaphores
Example: Two threads trying to increment a shared variable simultaneously
