(Financial: credit card number validation) Credit card numbers follow certain pat-
terns. A credit card number must have between 13 and 16 digits. It must start with:
4 for Visa cards
5 for Master cards
37 for American Express cards
6 for Discover cards
In 1954, Hans Luhn of IBM proposed an algorithm for validating credit card
numbers. The algorithm is useful to determine whether a card number is entered
correctly or whether a credit card is scanned correctly by a scanner. Credit card
numbers are generated following this validity check, commonly known as the
Luhn check or the Mod 10 check, which can be described as follows (for illustra-
tion, consider the card number 4388576018402626):
1. Double every second digit from right to left. If doubling of a digit results in a
two-digit number, add up the two digits to get a single-digit number.
4388576018402626
→ 2 * 2 = 4
→ 2 * 2 = 4
→ 4 * 2 = 8
→ 1 * 2 = 2
6 * 2 = 12 (1+ 2 = 3)
→ 5 * 2 = 10 (1+ 0 = 1)
→ 8 * 2 = 16 (1 + 6 = 7)
→ 4 * 2 = 8
(Algebra: solve 2 x 2 linear equations) You can use Cramer's rule to solve the
following 2 X 2 system of linear equation:
ed – bf
ax + by = e
cx + dy = f
af - eс
y
ad – bc
%3D
ad – bc
Write a program that prompts the user to enter a, b, c, d, e, and f, and displays the
result. If ad – bc is 0, report that "The equation has no solution."
(Sum the digits in an integer) Write a program that reads an integer between 0 and 1000 and adds all the digits in the integer. For example, if an integer is 932, the sum of all its digits is 14.

- (Display Magic Numbers) Display the first N magic numbers, where N is a positive number that the user provides as input. Here, a magic number is a number whose sum of its digits eventually leads to 1. For example, 1234 is a magic number because 1 + 2 + 3 + 4 = 10 and 1 + 0 = 1, while 1235 is not (1 + 2 + 3 + 5 = 11 and 1 + 1 = 2). Write a program that prints out the first N magic numbers, seven on each line. Here is the sample output: You are required to use the following function prototype: bool isMagic(int value); // Returns true if value is a magic number The outline of this function will be as follows: Step 1: Calculate the sum of digits of value Step 2: Repeat Step 1 until we get a single digit Step 3: If the resulting sum is equal to 1 then it is a magic number, otherwise notarrow_forward(Display Magic Numbers) Display the first N magic numbers, where N is a positive number that the user provides as input.

For example: Let us consider the number 145. Factorial sum = 1! + 4! + 5! = 1 + 24 + 120 = 145. Therefore 145 is a Krishnamurthy number. Other examples include: 1, 2, 40585. Write a program that does the following: • asks the user to input an integer. • computes whether the number is a Krishnamurthy number. • then finally prints the result.
