Password Verifier
Imagine you are developing a software package that requires users to enter their own passwords. Your software requires that user’s passwords meet the following criteria:
- The password should be at least six characters long.
- The password should contain at least one uppercase and at least one lowercase letter.
- The password should have at least one digit.

- Python languagearrow_forwardGPA Calculator Students are concerned about their GPA. They need to calculate it accurately every semester to monitor their progress. Develop a GPA calculator that follows the AOU regulations (AOU-OU Grade Scale) using C# programming language. The application asks the student to enter his numeric grade of each course and the course's credit hours. Accordingly, the application calculates the student's GPA after converting the numeric grade to letter grade. The GPA calculation should produce floating-point results. Display the results rounded to the nearest hundredth. You should store the letter grades of all student's courses in an array. The final grade of the student should be also calculated. Sample I/O Enter the course grade (-1 to end): 93 Enter the course credit hours: 3 Enter the course grade (-1 to end): 74 Enter the course credit hours: 2 Enter the course grade (-1 to end): 60 Enter the course credit hours: 3 Enter the course grade (-1 to end): -1 The grades of your courses…arrow_forwardC#arrow_forward
- C#arrow_forwardIntro to Python Programmingarrow_forwardPYTHON CODE Reza Enterprises sells tickets for buses, tours, and other travel services. Because Reza frequently mistypes long ticket numbers, Reza Enterprises has asked his students to write an application that shows if a ticket is invalid. Your application/program tells the ticket agent to enter a six-digit ticket number. Ticket numbers are designed so that if you lose the last digit of the number, then divide by 7, the remainder of the division is exactly the same to the last dropped digit. This process is shown below: Step 1: Enter the ticket number; for example 123454 Step 2: Remove the last digit, leaving 12345 Step 3: Determine the remainder when the ticket number from step 2 is divided by 7. In this case, 12345 divided by 7 leaves a remainder of 4. Step 4: Display a message to the ticket agent indicating whether the ticket number is valid or not. If the ticket number is valid, save the number to a .txt file called “tickets.txt” and continue to loop your program asking…arrow_forward
