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
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 decrementi
by 1 in each iteration (i--
). Sincei
is 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 ofi
will keep increasing, but without a condition to stop the loop, it will run forever.
