How is an infinite loop usually formed?

An infinite loop is typically created when a loop lacks a proper termination condition, which means that the loop will repeatedly execute without ever stopping. In programming, loops are designed to run a set of instructions until a certain condition is met. If that condition is omitted or if the condition is incorrectly set, the loop will continue to run indefinitely because there is no instruction or criteria to exit the loop.

For instance, in a while loop, if the condition is always true or if the variable checked in the condition is never updated within the loop body, the loop will ultimately never meet a stopping point. This leads to the infinite execution of the loop's code block. Understanding this concept is crucial for programmers to avoid situations where a program may hang, consume excessive CPU resources, or behave unpredictably.
