I'm making a program in Go for guessing a random number. , Identify the false statement. An infinite loop also called as endless loop or indefinite loop. An infinite loop -- sometimes called an endless loop -- is a piece of code that lacks a functional exit so that it repeats indefinitely. If the while loop condition never evaluates to False, then we will have an infinite loop, which is a loop that never stops automatically, in this case we need to interrupt externally. A finite loop executes a specific number of times; an indefinite loop is one that never ends. Increment. You can generate an infinite loop intentionally with while True. An Indefinite Loop Structure or Conditional Loop Structure iterates the body of the loop structure until certain conditions are met. In this case, you could give the user a finite amount of chances to enter a number and if they don't enter a valid value after that number of times, the loop exits. (T/F)A definite loop will terminate but an indefinite loop will never stop.
