Question

(True or False) The following is an infinite loop.

for(int i = 0; i < 5; --i)

{

cout << "Haha";

}

Answer 1

ANS : FALSE

Given , i=0 , condition for checking i< 5 and each time i is decarsing by 1.

because integer has range from -32768 to 32767 so first it will go from i=0 to i = -32767 then i will became 32767 which is greater than 5, so condition become false then it will stop,

for first iteration : i = 0, i<5 is true then it will print   haha

2nd iteration : i= -1 , i<5 is true then it will print haha

3rd iteration : i = -2, i<5 is true then it will prit haha

.

.

.

upto 32768 iterations,

32768 iteration i = -32768 , i<5 is true then it will print haha.

32769 iteration i = 32767 , i<5 is false then it will stop.

i hope this will help give an upvote.
