Question

Is the given answer correct?

Comments

it is 34
"printf("%d%d%d,a,b,c")" is 14 tokens

---

21????

---

I also write 21 but made easy people counted each token of that statement individually

I think their solution is wrong..!!

Answer 1

Total 34

"printf("%d%d%d,a,b,c")" 

will be considered as

"printf("      %      d         %         d        %          d      ,        a         ,        b       ,     c             ")"

NOT as 1 token but as 14 token

 srestha  may be i am wrong here but i think anything come between " " is a token.Please correct me i am wrong.
