Assignment 5 Due Monday October 20 630 Pmassigned Monday Sept

Write a program that performs the following tasks: 1) Read in a month and determine the number of days in the month. If the month is February, prompt the user for a year and determine if the year is a leap year to output the correct number of days. (A leap year is divisible by four, except for years with are multiples of 100, which are only leap years if they are also divisible by 400). Your program should accept the month as a 1 or 2 digit number, a three letter abbreviation for the month, or a full month. 2) Given someone’s birthday in the form mm/dd, m/dd, mm/d or m/d generates their sign and random advice (from at least four possibilities). 3) Write the truth tables for the following boolean expressions: a. A || B && C b. (A || B) && ! (A && B) 4) Strictly extra credit: Write a compatibility test for an online dating service. a. Have the two people enter their names. b. Calculate points as follows: i. If the two names are the same, they get -1 points and you do not have to check anymore ii. If the names of the same length add 2 points if the length of one name is 1 more than the other add one point iii. If the first letters are the same add 1 point iv. If the last letters are the same add 1 point v. If the last letter of one name is the same as the first letter of the other add 1 point (for both names) vi. Add the int values of the first letter of each name. take the value mod 3 and add it to the total. vii. Add the int values of the second letter of each name. take the value mod 4 and add it to the total. c. You should have anywhere from -1 to 11 points. Print off the points and a snarky comment appropriate for each one. Be sure to include their names in the message. Use this list to determine which comment to display: i. 11 points → comment 1 ii. 8 to 10 points → comment 2 iii. 5 to 7 points → comment 3 iv. 2 to 4 points → comment 4 v. 0 or 1 points → comment 5 vi. -1 points → comment 6 Sample test runs on the next two pages.

Paper For Above instruction

This comprehensive programming assignment encompasses four key tasks designed to assess and develop multiple skills in programming, logical reasoning, and data analysis.

Task 1: Determining the Number of Days in a Month

The initial task requires creating a program that reads a user's input representing a month and accurately determines the number of days in that month. The program should accept various formats for the month input, including a one or two-digit number, a three-letter abbreviation, or the full name of the month. Special consideration is given to February, where the program must prompt for the year to correctly identify leap years. The leap year calculation follows the standard rules: a year is a leap year if it is divisible by 4; however, years divisible by 100 are not leap years unless they are also divisible by 400. This ensures accurate determination of February’s days, which can be 28 or 29.

Task 2: Generating Zodiac Signs and Advice Based on Birthdays

The second component involves parsing a person's birthday provided in various formats such as mm/dd, m/dd, mm/d, or m/d. The program must then determine the zodiac sign associated with that birthday and generate a random piece of advice from at least four possible options. This functionality requires implementing date parsing logic, mapping dates to zodiac signs, and associating each sign with contextual advice, demonstrating proficiency in string manipulation, conditional logic, and randomization techniques.

Task 3: Logical Boolean Expression Truth Tables

The third task involves designing truth tables for two Boolean expressions:

  • Expression a: A || B && C
  • Expression b: (A || B) && !(A && B)

Creating these tables entails enumerating all possible truth values for A, B, and C (true or false) and evaluating the expressions based on logical operator precedence. This task emphasizes understanding of Boolean algebra, operator precedence, and truth table construction.

Extra Credit: Compatibility Test for an Online Dating Service

The extra-credit challenge involves designing a compatibility scoring algorithm based on user names:

  1. Prompt both users for their names.
  2. Compute compatibility points following these steps:
    • If the names are identical, assign -1 points and skip further checks.
    • If the names share the same length, add 2 points; if the length difference is exactly 1, add 1 point.
    • Check if the first letters are identical; if so, add 1 point.
    • Check if the last letters are identical; if so, add 1 point.
    • Compare the last letter of one name to the first letter of the other; if they match, add 1 point, and vice versa.
    • Add the integer value of the first letter of each name, compute its modulus with 3, and add the result.
    • Similarly, add the integer value of the second letter of each name, compute its modulus with 4, and add the result.
  3. The total points can range from -1 to 11. Based on the total points, display an appropriate snarky comment from a predefined list, including the users' names in the message. The comments vary depending on the score bracket, ranging from highly compatible to incompatible.

Conclusion

This assignment synthesizes several core programming skills, including input handling, conditional logic, parsing, Boolean algebra, and creative output generation. The tasks encourage not only technical proficiency but also logical thinking and user interaction. Successful completion demonstrates a well-rounded understanding of fundamental programming concepts applicable across diverse computational problems.
