Question

Question...

for (i=2; i<=20; i++)
{ cout<<"Hello";}

Ans = 19 times .

Now explain me, how do we get 19..? And what does this mean..
​

Answer 1

Answer:

It came 19 because we gave the system the info toh print hello less or equal to 20 starting from 2.

Answer 2

Answer:

the loop iterates from 2 to 20

count from 2 till 20

you'll get 19...

when it becomes 21...the value no longer satisfies the <=20 condition

so the loop stops
