Please Help Me With These Two Programs1write A Console App Called Mo

Please help me with these two programs 1. Write a console app called MonthChecky that prompts a user to enter a month number (a digit from 1-12). If the value entered is out of range (greater than 12 or less than 1) display a meaningful error message, otherwise display a message indicating that the month entered is valid. USE ONLY NAMED CONSTANTS 2. There is a fish day care center called Fish-O-Rama. They need a console app that will calculate the daily fish care fee based on a fish's size. The program must accept the following from the user: Customer Name, Fish Name, Fish Species, and Fish Length (in inches). Once the data has been entered, the program should display all of the entered data, as well as the daily fish care fee, calculated as follows: $7 for fish under 10", $12 for fish 10" to 20" inclusive, $16 for fish greater than 20" and up to 30", and $20 for fish greater than 30". USE ONLY NAMED CONSTANTS FOR ALL FISH SIZES AND FEES. In your output, demonstrate that it calculates the correct fee for several (at least three) different sizes of fish.

Paper For Above instruction

This paper addresses the development of two simple console applications in C# that demonstrate fundamental programming concepts such as user input handling, conditional statements, and the use of constants to enhance code readability and maintainability. The first application, named MonthChecky, prompts the user to enter a month number between 1 and 12 and validates this input, displaying an appropriate message based on the validity of the input. The second application models a fish daycare billing system called Fish-O-Rama, calculating daily fish care fees based on the size of the fish entered by the user, again emphasizing good programming practices through the use of constants for all size thresholds and fee values.

MonthChecky Application

The primary goal of the MonthChecky application is to verify that user input corresponds to a valid calendar month. To achieve this, the application uses named constants to define the minimum and maximum acceptable month numbers, namely 1 and 12. This approach not only improves code clarity but also simplifies future modifications. The program prompts the user for input, parses the input to an integer, and then evaluates whether this value falls within the valid range. If the input is invalid, a meaningful error message is displayed; otherwise, the user is informed that the month is valid.

This validation process incorporates error handling to accommodate non-numeric or malformed input, ensuring robustness. Using constants such as MIN_MONTH and MAX_MONTH, the program exemplifies best practices in coding standards and readability.

Fish-O-Rama Billing System

The second program models a simplified billing system for the Fish-O-Rama fish daycare center. This application gathers information from the user—customer name, fish name, species, and size in inches—and then calculates the daily care fee based on predefined size thresholds. All size categories and corresponding fees are defined as named constants, facilitating maintainability and clarity.

The program employs conditional logic to determine the correct fee based on the entered fish size. For example, fish less than 10 inches incur a $7 fee, those between 10 and 20 inches (inclusive) cost $12, fish larger than 20 inches up to 30 inches cost $16, and fish exceeding 30 inches cost $20. After collecting and validating the input, the program displays all the entered data along with the calculated fee. To demonstrate correctness, multiple size inputs are processed, illustrating the accuracy and flexibility of the program.

Implementation Concerns

Both applications emphasize the importance of constants for fixed values, input validation to prevent errors, and clear output formatting. These principles are essential for developing reliable, easy-to-maintain software solutions. The use of constants also reduces the likelihood of errors caused by magic numbers, and improves code readability.

Conclusion

Developing basic console applications as described not only enhances programming skills but also lays the groundwork for more complex systems. Proper use of constants, robust input validation, and clear user communication are fundamental components of high-quality software. These simple programs can serve as educational tools and building blocks for more sophisticated applications in the future.
