Chapter 12, Problem 12PE

Password Weakness Detector

Design a program that asks the user to enter a password, and then analyzes the password for the following weaknesses:

• Fewer than 8 characters
• Does not contain at least one uppercase letter and one lowercase letter
• Does not contain at least one numeric digit
• Does not contain at least one special character (a character that is not a letter or a numeric digit)
• Is a sequence of consecutive uppercase letters (such as ABCDE)
• Is a sequence of consecutive lowercase letters (such as abcde)
• Is a sequence of consecutive numeric digits (such as 12345)
• Is a repeating sequence of characters (such as ZZZZZ or 55555)

The program should display messages indicating whether any of these weaknesses are found in the password.
