A password is required to be 12 to 16 characters in length. Characters can be digits (0-9), upper or lower-case letters (A-Z, a-z) or special characters. There are 10 permitted special characters. There is an additional rule that not all characters can be letters (i.e. there has to be at least one digit or one special character) ow many permitted passwords are there?

Problem 1 (12 points): In this problem you will count the number of passwords with certain characteristics. The characters in the passwords are all either letters or digits. You can assume all letters are lower case, so there are only 26 letters. State how many passwords there are with the given restrictions: 1. Length is 6 or 7 2. Length is 6 and it must contain at least one digit. 3. Length is 6 and it must have at least...

Question 3: a. A computer password is 6 characters long. A character can be either a digit or an uppercase English letter. A valid password must contain exactly one digit. How many valid passwords are there? (hint: you do not know the position of this one digit. It might be in the beginning or the end or the middle of the password. You may use the combination low to select the position of this digit and then assigno value to...

JAVA Problem: With the recent news about data breaches and different organizations having their clients’ information being exposed, it is becoming more and more important to find ways to protect our sensitive data. In this program we will develop a simple tool that helps users generate strong passwords, encrypt and decrypt data using some cyphering techniques. You will need to create two classes. The first class is your driver for the application and contains the main method. Name this class...

This C++ Program consists of: operator overloading, as well as experience with managing dynamic memory allocation inside a class. Task One common limitation of programming languages is that the built-in types are limited to smaller finite ranges of storage. For instance, the built-in int type in C++ is 4 bytes in most systems today, allowing for about 4 billion different numbers. The regular int splits this range between positive and negative numbers, but even an unsigned int (assuming 4 bytes)...
