Write a program that prompts the user to input two POSITIVE numbers — a dividend (numerator) and a divisor (denominator). Your program should then divide the numerator by the denominator. Lastly, your program will add the quotient and the remainder together.

 rem = Math.abs(num) % Math.abs(den)

Math.abs() is a function to make the integer a positive integer so that negative integers cant be divided

Write a program that reads a monetary amount in dollars and cents (such as 37.84) and computes the equivalent in bills and coins, using the largest denominations possible.

Use a Scanner object to read in a double value for the monetary amount
Convert the total monetary amount to an integer representing the total number of cents (there are 100 cents in a dollar)
US monetary denominations
ten dollar bill = 1000 cents
five dollar bill = 500 cents
one dollar bill = 100 cents
quarter coin = 25 cents
dime coin = 10 cents
nickel coin = 5 cents
penny coin = 1 cent
Use integer division (/) and modulus (%) to calculate each denomination and the cents left over
Hint: You will need to successively divide the remaining cents by the number of cents in the denomination, starting with the ten dollar bills.
tens = remainingCents / 1000; // Divide the total cents by the number of cents in $10
remainingCents = remainingCents % 1000; //Remainder of division by 1000 is what is left after $10 bills taken out
When user input appears as shown in Figure 1, your program should produce output as shown in Figure 2.

Figure 1: (input)

37.84
Figure 2: (output)

$37.84 is equivalent to the following:
3 ten dollar bills
1 five dollar bills

Using the knowledge of computational language in python we can write the code as program that reads a monetary amount in dollars and cents (such as 37.84) and computes the equivalent in bills and coins, using the largest denominations possible.

Writting the code:

int one, five, ten;

int penny, nickel, dime, quarter;

// Create a Scanner object to read input.

Scanner kb = new Scanner(System.in);

// Get the user's amount

System.out.print("What is the amount? ");

amount = kb.nextDouble();

// Calculations

ten = (int) (amount / 10);

amount = amount % 10;

five = (int) (amount / 5);

amount = amount % 5;

one = (int) (amount / 1);

If you forget your password for a website and you click [Forgot my password], sometimes the company sends you a new password by email but sometimes it sends you your old password by email. Compare these two cases in terms of vulnerability of the website owner.

If the site tells you what your password was, that means the site is storing your password rather than just a hash of it. This means that anyone who gains access to the site’s password database has access to all the passwords. If the site sends you a temporary password, there is a good chance it is not storing actual passwords, which is the correct approach from a security perspective.

Answers

I believe the first one is better but in regards to the two cases in terms of vulnerability of the website owner, one can say that when the owner to  the site is breached into, a lot of people's account will be breached into also and personal information stolen.

Why the above idea?

If a person is said to click forgot password button on a site, the  email that is said to have their old password will be sent a new Passwords from the website in question.

But this is one that is not often secure based on the fact that the system admins and programmers  will be seeing the  password.

On the  other hand, let say  the site sends a new password without carrying out any kind of proper validation and whoever that has asked  for the new password, the new password may fall into the hands of those who it is being sent to and this may be an intruder therefore, it is one that is also risking website owners and users as well.

Hence, I believe the first one is better but in regards to the two cases in terms of vulnerability of the website owner, one can say that when the owner to  the site is breached into, a lot of people's account will be breached into also and personal information stolen.
