CHALLENGE🔥🔥🔥: Sam wants to select a username to register on a website. The rules for selecting username:

Question

1. The minimum length of the username must be 5 characters and the maximum may be 10.
2. It should contain at least one letter from A-Z
3. It should have at least one digit from 0-9
4. It should have at least one character from amongst @#*=
5. It should not have any spaces

Write a program which accepts 4 usernames (one username per line) as input and checks whether each of them satisfy the above mentioned conditions.
If it does, the program should print PASS (in uppercase) else print FAIL

Happy Coding😉

Answer 1

@George, here's my attempt:

Answer 2

@Ipang both uppercases(A) and lowercase(a) can be used and 1_B@# should be a PASS since it an underscore(_) not a space( )
Thanks for the correction.

Happy Coding 😉

Answer 3

@lpang yeah only the four characters are required for instance:

Suppose the following usernames are supplied to the program:
1234@a
ABC3a#@
1Ac@
ABC 3a#@
1_B@#

Then the output should be:
PASS
PASS
FAIL
FAIL
FAIL

Answer 4

Hi @George Victor, I just need to confirm about point 4, are those four the only characters needed to be checked for existence? how about hyphen, underscore, tilde or period? are they not valid to be in a username?

Thanks : )

Answer 6

@George, I am sorry I need to ask again, does alphabet letter case matter? I mean, if there exists only lowercase, and no uppercase, is that valid for name or no? also for that last one, why it failed the test?

1Ac@ <- FAILED - too short
ABC 3a#@ <- FAILED - contains space
1_B@# <- Why FAILED? it has letter, number, both @ and #

Thanks

Answer 7

@George thanks for the confirmation, I will try to do this and get back to you later : )

Answer 13

Had a go at this, and made as much sense of the rules as I could:

Answer 14

Hey @CuRSeD, it is a constant that we can use to verify whether or not the character we want to find exists in some string where we search for the character. The string class' find() method returns that constant when the character is not found in the string.

P.S. Sorry I forgot to set the code public, you could've commented on it instead writing in here if I had : )

Hth, cmiiw
