Problem Descriptionwrite A Program That Prompts The User To Enter The

Write a program that prompts the user to enter the year and displays the Chinese Zodiac for the year. The Chinese Zodiac is based on a twelve-year cycle, each year being represented by an animal: rat, ox, tiger, rabbit, dragon, snake, horse, sheep, monkey, rooster, dog, and pig, in this order. Note: 1900 is the year of the rat.

Sample runs:

  • Enter a year: 1963rabbit
  • Enter a year: 1877ox

Paper For Above instruction

The Chinese Zodiac is an integral part of Chinese astrology and cultural tradition, representing a repeating 12-year cycle, each associated with a specific animal sign. Determining the Zodiac sign for a given year involves calculating the year's position within this cycle, typically using modular arithmetic. A simple program can be developed to prompt the user for a year and then display the corresponding Zodiac animal based on this cycle.

The logic behind this program is straightforward: since 1900 corresponds to the rat, and the cycle repeats every 12 years, the key is to calculate the difference between the input year and 1900, then find the remainder when dividing by 12. This remainder maps directly to an animal in the sequence. For example, if the remainder is 0, the animal is rat; if 1, ox; 2, tiger; and so forth, until 11, pig.

The implementation begins with prompting the user for an input year. Then, the program computes the offset from the base year (1900), applies modulo 12, and uses a predefined array or list of animal names to output the corresponding Zodiac sign. This approach ensures that the program is simple, efficient, and easily adaptable for any year input.

Understanding user interaction and basic control structures such as arrays and modular arithmetic is essential. This demonstrates how straightforward computational logic can be applied to culturally significant data, bridging programming principles with real-world applications.

Implementation:

Below is a detailed Python implementation of the described logic to identify the Chinese Zodiac sign for any given year, including input validation and output formatting.



def get_chinese_zodiac(year):


animals = ["rat", "ox", "tiger", "rabbit", "dragon", "snake",


"horse", "sheep", "monkey", "rooster", "dog", "pig"]


Calculate the index based on the base year 1900


index = (year - 1900) % 12


return animals[index]


def main():


try:


year_input = input("Enter a year: ")


year = int(year_input)


zodiac = get_chinese_zodiac(year)


print(zodiac)


except ValueError:


print("Invalid input. Please enter a valid year.")


if __name__ == "__main__":


main()

This program efficiently determines the Zodiac sign associated with any year entered by the user, leveraging modular arithmetic and array indexing.

Conclusion

Developing a program to find the Chinese Zodiac sign for any year illustrates practical application of modular arithmetic and array data structures. It emphasizes user input handling, basic algorithm development, and cultural knowledge integration in software solutions. Such programs can be expanded or incorporated into larger systems, such as calendars, astrology apps, or educational tools, demonstrating the value of simple programming constructs in real-world contexts.
