Answer 1

Your logic is wrong, the count will be updated every time when the resultant value of "if" becomes 0.

See if this helps-

Answer 2

Remove first line from your Code and Check again.

Answer 3

Sayeef A prime number can only be divisible by 1 and the number itself so only when count becomes 2 it is possible.

Do you get it now?

Answer 4

Yes, thank you Avinesh

Answer 5

Avinesh I know it's right but can't seem to wrap my head around how count==2 makes it logical for primes to increase by 1
