Doubts about the number of times in the Membership test

Question

https://code.sololearn.com/cif4yWnX56YJ
This is a code that I wrote today
I want to check the password of the account number three times.
but this code allows four attempts,
what went wrong?

Answer 1

You asked before the loop started.
I suggest using a do while.
Or, fix by just leaving username and pin undeclared before the loop.

username = "";
pin = "";

Answer 2

thanks very much!
