Thread safety
Thread safety is a crucial idea in computer science and programming. In the current world, where applications can run in parallel both locally and remotely, being able to write code that multiple processes can execute simultaneously plays a crucial role in software development.
Imagine a C++ first-person platform game with functions that allow the player to perform actions such as moving and jumping, computer-generated characters that can attack the player, and a user interface that keeps the player updated with the most relevant information about the status of the game (i.e., points, health, etc.). In this context, all those functions must be thread-safe. If the functions are not thread-safe, the game can behave unpredictably. For example, the player could end up interacting with a piece of a computer-generated object that is not in that spot anymore, or they may see a status of their actions that is outdated or incorrect.
This example includes the main concerns...
