Understand multithreading and synchronization from "summary" of C/C++ Programmer's Reference by Herbert Schildt
Multithreading allows multiple threads to exist within the context of a single process. Each thread has its own stack and runs independently, but shares the same global memory space. This allows for concurrent execution of code, which can improve performance by taking advantage of multiple processors or processor cores. However, multithreading also introduces the potential for synchronization issues. Synchronization is the process of coordinating the execution of multiple threads to ensure that they do not interfere with each other. Without proper synchronization, threads can access shared resources simultaneously, leading to data corruption or inconsistent results. To prevent this, programmers use synchronization techniques such as locks, semaphores, and mutexes to control access to shared resources. Locks are the most basi...
