Code get stuck with nested loop and computer crashes after (2024)

FAQs

Can a while loop crash your computer? ›

If you don't have a super CPU you will immediately crash most browsers with that loop and anything that doesn't crash won't work and will take up most of CPU. While the code is stuck in that loop JS can't do anything else like run the events, so game can never get set to true, and the loop can never end.

Infinite loops occur when loops have no exit condition (no way to stop) so when the program is run it loops forever with no break, causing the browser to crash. This happens most often with while loops, but any kind of loop can become infinite.

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 a user.

However, abnormally high CPU usage can cause the computer to stutter, become unresponsive, or crash. If your computer seems to overwork its CPU even when high-intensity applications are closed, it may indicate a deeper problem.

Infinite loops can cause various problems, such as freezing your program, consuming your CPU resources, or producing unwanted outputs.

Infinite loops are loops for which the condition will always be true. The problem is that you can't determine whether that will happen for every possible loop. It's a case of the Halting Problem. There's no universal way to determine that a program (or in this case, a loop) will terminate.

Infinite loops are a pain. In general, running an infinite loop can eat up your computer's resources and then freeze your IDE—and sometimes even your whole machine. Inside the CodeSignal IDE, letting infinite loops run unchecked would eventually slow down or crash the UI.

This is sometimes invaluable, but comes with a danger: sometimes your while loop will never stop! This is called an “infinite loop”. If the condition stays true, the while loop will keep on executing the block — until the end of the universe, if need be. This is usually not what you want!

The code inside of the while loop does not modify the variable counter , so the halting condition will never evaluate to false. This loop will run forever (or until the program is stopped). Infinite loops cause headaches for programmers and users alike because the program itself can never move forward.

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.
