The form for (;;) for an infinite loop is traditional, appearing in the standard reference The C Programming Language, and is often punningly pronounced "forever". [11] This is a loop that will print "Infinite Loop" without halting. A similar example in 1980s-era BASIC:
Circular references like the above example may return valid results if they have a terminating condition. If there is no terminating condition, a circular reference leads to a condition known as livelock or infinite loop , meaning it theoretically could run forever.
Unlike coroutines, if a virtual thread is in an infinite loop, it does not block the program. Execution continues at a higher cpu load, even if there are more looping threads than available execution units; Virtual threads can number in the tens of millions by featuring small often managed stacks
Some infinite loops can be quite useful. For instance, event loops are typically coded as infinite loops. [1] However, most subroutines are intended to finish. [2] In particular, in hard real-time computing, programmers attempt to write subroutines that are not only guaranteed to finish, but are also guaranteed to finish before a given deadline ...
In computer science, a for-loop or for loop is a control flow statement for specifying iteration. Specifically, a for-loop functions by running a section of code repeatedly until a certain condition has been satisfied. For-loops have two parts: a header and a body. The header defines the iteration and the body is the code executed once per ...
In computer science, a generator is a routine that can be used to control the iteration behaviour of a loop.All generators are also iterators. [1] A generator is very similar to a function that returns an array, in that a generator has parameters, can be called, and generates a sequence of values.
A conditional loop has the potential to become an infinite loop when nothing in the loop's body can affect the outcome of the loop's conditional statement. However, infinite loops can sometimes be used purposely, often with an exit from the loop built into the loop implementation for every computer language , but many share the same basic ...
For example, in 2011, Oracle issued a security fix for a bug in the Double.parseDouble method. [2] This method converts a string such as "12.34" into the equivalent double-precision floating point number. The bug caused this method to enter an infinite loop when called on a specific input.
