Question
Which of the following for loops will be an infinite loop? for(; ;)for(i=0 ; i<1; i--) for(i=0; ; i++) All of the above
Solution 1
All of the above will result in an infinite loop.
-
for(; ;): This loop will run indefinitely because there is no condition specified to terminate the loop. -
for(i=0 ; i<1; i--): This loop will also run indefinitely. The initial condition isi=0, and the loop will decrementiby 1 in each iteration (i--). Sinceiis always less than 1, the loop will never terminate. -
for(i=0; ; i++): This loop will run indefinitely because there is no condition specified to terminate the loop. The value ofiwill keep increasing, but without a condition to stop the loop, it will run forever.
Solution 2
All of the above will result in an infinite loop.
-
for(; ;): This loop will run indefinitely because there are no conditions to stop it. -
for(i=0 ; i<1; i--): This loop will also run indefinitely because the conditioni<1will always be true asiis decreasing. -
for(i=0; ; i++): This loop will run indefinitely because there is no condition to stop it. The value ofiwill keep increasing but without a condition to break the loop, it will continue indefinitely.
Solution 3
All of the above
Explanation:
-
for(; ;): This loop will run indefinitely because there is no condition specified to stop the loop. -
for(i=0 ; i<1; i--): This loop will also run indefinitely because the loop counteriis decreasing each time, so it will always be less than 1. -
for(i=0; ; i++): This loop will run indefinitely because there is no condition specified to stop the loop. The loop counteriwill keep increasing, but without a condition to check, the loop will never stop.
