- Q1: Write a C++ program to calculate the diagonal of a rectangle. Users are required to enter the length and width of the rectangle. If you enter negative values for length and width, you will receive a display message indicating incorrect input. Afterward, after verifying the validity of these variables, the rectangle's diagonal is calculated and displayed. Recall that d = vw² + 1².(1) Prompt the user for a string that contains two strings separated by a comma. (1 pt) Examples of strings that can be accepted: Jill, Allen Jill , Allen Jill,Allen Ex: Enter input string:Jill, Allen (2) Print an error message if the input string does not contain a comma. Continue to prompt until a valid string is entered. Note: If the input contains a comma, then assume that the input also contains two strings.

- (Conversion) a. Write a C++ program to convert meters to feet. The program should request the starting meter value, the number of conversions to be made, and the increment between metric values. The display should have appropriate headings and list the meters and the corresponding feet value. If the number of iterations is greater than 10, have your program substitute a default increment of 10. Use the relationship that 1 meter = 3.281 feet. b. Run the program written in Exercise 6a on a computer. Verify that your program begins at the correct starting meter value and contains the exact number of conversions specified in your input data. c. Modify the program written in Exercise 6a to request the starting meter value, the ending meter value, and the increment. Instead of the condition checking for a fixed count, the condition checks for the ending meter value. If the number of iterations is greater than 20, have your program substitute a default increment of (ending value - starting value) / 19.Q1) Write a password changer program in Python. Be creative with how you change passwords - strong passwords have a mix of lowercase letters, uppercase letters, numbers, and symbols with minimum length 5. The program should check whether the previous password entered by user is correct or not. Check the length of new password also The left question in the photoii) Your neighbour always keeps the wifi password after modifying the wifi name using some rules. The rules are: a) If there is a digit d in wifi name, then it will be 9-d in the password. b) Case of every alphabet is changes, i.e. upper to lower and lower to upper. c) Any other characters remain same. Write a C++ program in which you input the wifi name and the program prints the wifi password.
- Parking Charges) A parking garage charges a $2.00 minimum fee to park for up to threehours and an additional $0.50 per hour for each hour or part thereof over three hours. The maximumcharge for any given 24-hour period is $10.00. Assume that no car parks for longer than 24 hoursat a time. Write a program that will calculate and print the parking charges for each of three customers who parked their cars in this garage yesterday. You should enter the hours parked for eachcustomer. Your program should print the results in a tabular format, and should calculate and printthe total of yesterday's receipts. The program should use the function calculateCharges to determine the charge for each customer. Your outputs should appear in the following format:Car Hours Charge1 1.5 2.002 4.0 2.503 24.0 10.00TOTAL 29.5 14.50Q1/ Write a program that reads from the user the number of students in the class and their grades in one class, the program must find the largest and the lowest grades with the sequence of students and then find the average grade of the class, see the example below:Programming language: c++ (1) Prompt the user for a string that contains two strings separated by a comma.

- THIS IS FOR C++ ONLY Part 2b: Password Verification A secure password is critically important in today's world. Organizations typically have stringent requirements to ensure a password is complex enough so as not to be easily hacked. Write a program that will accept as input a potential password and determine whether or not it is valid in meeting the following criteria: at least eight characters long at least one uppercase letter at least one lowercase letter at least one digit at least one special character (you can determine what is acceptable) If the password is valid, ask the user to enter it again. If it matches, indicate the password has been accepted. If the password does not meet any of the above criteria, indicate which it does not meet.(1) Prompt the user for a string that contains two strings separated by a comma • Examples of strings that can be accepted: • Jill, Allen • Jill, Allen • Jill, Allen Ex: Enter input string: Jill, Allen (2) Print an error message if the input string does not contain a comma. Continue to prompt until a valid string is entered.
