Can while be empty?
However, an empty condition is not legal for a while loop as it is with a for loop. while loop says “Execute this block of code, and then continue to loop while the condition is true”.
Can you have an empty while statement?
Yes an empty while loop would generally be seen as a bad thing, though there are a few useful cases too. No, you should not do something like that. It uses 100% of the CPU and that is not useful.
How do you break a one loop?
The break statement exits a for or while loop completely. To skip the rest of the instructions in the loop and begin the next iteration, use a continue statement. break is not defined outside a for or while loop. To exit a function, use return .
What does an empty while loop do?
An empty loop is a loop which has an empty body, e.g. Infinite for loop is a loop that works until something else stops it.
Can a thread not exit a while loop?
Now typically in an embedded system the main thread will typically not (or at least probably shouldn’t) exit: The key point here is that so long as the threads entry function does not exit/return, the thread will stay in existence. However this does not necessarily mean that the thread has to be actively executing code:
How to determine when a thread is in the running state?
Although I’m having a bit of trouble (probably too rusty with C++) determining when the Thread is in the Running state via get_state (), I did printf the State of the Thread in various scenarios. Here is what I have seen: Thread state is Running (1) after creation, then is WaitingMailbox (8) during while (1) loop
What can the thread1 object be used for?
The thread1 object can be used to query the status of the execution of the threads function (and any child functions) – i.e if it is ready to run, running, waiting, inactive, etc). Now, it is important to remember that any single-core processor can only execute a single instruction at a time.
When does the main thread exit the program?
Execution begins sequentially one line at a time (jumping to other functions if they are called, and returning when they end). In the above example, the program will eventually exit. Now typically in an embedded system the main thread will typically not (or at least probably shouldn’t) exit:
