Question
A password must start with a letter, be at least 6 characters long, include a number, not include any whitespace, and include a special symbol. How many of the following passwords are valid?hello, goodbye, Maker1, dog!three, Oops_again, 1augh#3
Solution
To determine the validity of the passwords, we need to check each one against the given criteria. Let's go through them one by one:
-
"hello": This password starts with a letter, but it is not at least 6 characters long, does not include a number, and does not include a special symbol. Therefore, it is not valid.
-
"goodbye": This password starts with a letter and is at least 6 characters long, but it does not include a number or a special symbol. Therefore, it is not valid.
-
"Maker1": This password starts with a letter, is at least 6 characters long, and includes a number. However, it does not include a special symbol. Therefore, it is not valid.
-
"dog!three": This password starts with a letter, is at least 6 characters long, and includes a special symbol. However, it does not include a number. Therefore, it is not valid.
-
"Oops_again": This password starts with a letter and is at least 6 characters long, but it does not include a number or a special symbol. Therefore, it is not valid.
-
"1augh#3": This password does not start with a letter, but it is at least 6 characters long, includes a number, does not include any whitespace, and includes a special symbol. However, because it does not start with a letter, it is not valid.
So, none of the given passwords are valid according to the specified criteria.
