loop (or endless loop) is a sequence of instructions in a computer program which loops endlessly, either due to the loop having no terminating condition, having one that can never be infinite loop comic met, or one that causes the loop to start over. In older operating systems with cooperative multitasking, infinite loops normally caused the entire system to become unresponsive. With the now-prevalent preemptive multitasking model, infinite loops usually cause the program to consume all available processor time, but can usually be terminated by the user. Busy wait loops are also sometimes called "infinite loops". One infinite loop python possible cause of a computer "freezing" is an infinite loop; others include thrashing, deadlock, and access violations.

An infinite loop occurs when the condition will never be met, due to some inherent characteristic of the loop. Intentional looping[edit] There are a few situations when this is desired behavior. For example, the games on cartridge-based game consoles typically have no exit condition in their main loop, as there is no operating system for the program to exit to; the loop runs until the console is powered off. Modern interactive computers require that the computer constantly be monitoring for user input or device activity, so at some fundamental level

Notice that even though it https://en.wikipedia.org/wiki/Infinite_loop does not have any syntax errors it still does not run properly. The system will display the following message: Arithmetic exception (core dump) The operating system will create a new file in your current directory called core. This file contains a copy of the system memory at the time your program aborted because of the run time error. This file may only http://www.csc.villanova.edu/~lab/unix/runtime.html be used by more advanced programmers to debug obscure errors. It is of no use to us at this time and it is occupying a large amount of your disk quota (you can check this by typing the command ls -l). Just remove it now by entering: rm core Remember to remove the core file whenever your program has a run time error. ILLEGAL INPUT:There are many types of run time errors. Another common type is when a program is expecting input of a certain type, for example an integer, but encounters input of a different type, for example, a character. Run your add program but this time, when the program prompts you to enter an integer, enter the character "X" and watch what happens. This is one of the major difficulties with the C language: it always assumes that you know what you are doing!! You can see that the result is erroneous. INFINITE LOOP:Another type of run time error is the infinite loop. You may have already covered the loop programming construct in class. A program loop allows us to ind

The error normally occurs under a Direct3D or OpenGL application, on systems using a GeForce 2 or GeForce 3 video card with WinXP and the Nvidia detonator drivers 23.11 or 21.83. There are reports, however, of the issue occurring under Win2K. There are also reports of this occurring with ATI video cards but this has not been confirmed by VIA. OpenGL- spontaneous reboot, hardware lockup or insufficient virtual memory error from WinXP Direct 3D - Hardware lockup, BSOD with a message about an infinite loop error with a Nvidia driver BSOD error message - this varies but refers to a problem with "nv4_disp.dll" Here is the page that describes the different steps you can try to solve this problem. http://www.viaarena.com/?PageID=64 What are the symptoms of this error?

To better learn from and remember it, I'd like to know if this type of error has a name or some definition. (The error itself OutOfMemoryError isn't unusual, I'm talking about what lead to this error). My (simplified) situation was this: I had a class Singleton: class Singleton extends ClassA{ private static Singleton instance; private Singleton(){ // implicitly calls super() } public static Singleton getInstance(){ if (instance==null) instance = new Singleton(); return instance; } } And it's superclass ClassA: abstract class ClassA{ public ClassA(){ ClassB objectB = new ClassB(); // .. some logic .. } } And a class ClassB that uses Singleton in it's constructor: class ClassB{ public ClassB(){ Singleton singleton = Singleton.getInstance(); // .. some logic .. } } What happens is the following: 1- ClassB is instantiated somewhere. It's constructor is invoked and calls Singleton.getInstance(). 2- Singleton.getInstance() sees that instance == null and executes instance = new Singleton(). 3- The constructor of Singleton is run. It's empty, but it implicitly calls the superclass' (ClassA) constructor. 4- The superclass of Singleton instantiates a ClassB object new ClassB(). 5- ClassB's constructor is invoked and calls Singleton.getInstance()... Since the instantiation of instance in Singleton never reached it's finish, instance == nul
