The general case depends on whether the threads are wholly independent of each other. If you go multi-threaded, you must ensure that any shared resource is accessed appropriate protection. The code shown has a shared resource in the use of srand() and rand(). You will get different results in a multi-threaded process compared with those … Read more
Long story short, the Pi is too complex hardware-wise to operate without an OS (for the vast majority of tasks, anyway). An operating system is essentially an environment for your program to work in. It provides standardized means to use and manage hardware, interrupts, storage (incl. filesystems), I/O etc. What is more inportant, it does … Read more
