Thread: Infinite loop syntax question

These are things programmers generally avoid like the plague... So forgive my curiosity as to why you need to do this...

It is rather common in embedded code to have an endless loop at the end of small test programs.

Note: to OP I am trying to write my embedded code so I can test it with normal C compilers to verify simple unit tests. But, I am my own test team. It seems much easier/faster to test the code on a normal PC than on a micro-controller. I still have to test on the micro-controller; but, it reduces the problems found at that point.

Code:

While(1)
{}

It should be like this. Because after while you can not use ";". At least I know that so.

You are wrong; but, many people do it that way because it means it was on purpose instead of an accident ";".

Really? ı didn t know this. Thanks.

Consider this code...

Code:

while (getchar() != '\n');

Which is commonly used to empty the keyboard buffer between inputs.
