3.a. Write a for loop that prints the ASCII code of each character in a string named S. Usethe built-in function ord(character) to convert each character to an ASCII integer.b. Next, change your loop to compute the sum of the ASCII codes of all characters in a string
15) Write a program to retrieve two numbers from a user, and swap those number using only the XOR operation. You should not use a temporary variable to store the numbers while swapping them. Your program should include a proper and useful prompt for input, and print the results in a meaningful manner.
16) Using only sll and srl, implement a program to check if a user input value is even or odd. The result should print out 0 if the number is even or 1 if the number is odd. Your program should include a proper and useful prompt for input, and print the results in a meaningful manner.

For example, if 11 is passed, it will return 1 + 3 + 5 + 7+9 + 11. Do this using for loop.arrow_forward(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 = 8arrow_forward
- (1) Prompt the user to enter a string of their choosing. Output the string. (1 pt)Ex: Enter a sentence or phrase: The only thing we have to fear is fear itself. You entered: The only thing we have to fear is fear itself. (2) Complete the get_num_of_characters() function, which returns the number of characters in the user's string. We encourage you to use a for loop in this function. (2 pts) (3) Extend the program by calling the get_num_of_characters() function and then output the returned result. (1 pt) (4) Extend the program further by implementing the output_without_whitespace() function. output_without_whitespace() outputs the string's characters except for whitespace (spaces, tabs). Note: A tab is '\t'. Call the output_without_whitespace() function in main(). (2 pts)Ex: Enter a sentence or phrase: The only thing we have to fear is fear itself. You entered: The only thing we have to fear is fear itself. Number of characters: 46 String with no whitespace:…arrow_forward1) Output all numbers which can be fully divided by 3, 5, 7 at the same time from 1 to 1000.arrow_forward5.
