Calculate Updated Salary: Write A Program That Calculates ✓ Solved

Calculate updated salary Write a program that calculates the updated salary for an employee

Develop a program that computes an employee's updated salary based on user input or data from a file. The program should prompt the user for their full name, employment status, current salary, and pay increase percentage. It should then display the new salary formatted to two decimal places. Additionally, the program must process a file containing multiple employees' data, compute each updated salary, and save the results to an output file.

The first part involves creating an interactive program (question 1) that accepts live input and displays the updated salary for a single employee. The second part involves reading employee data from a specified input file, calculating the new salaries, and writing the results to an output file (question 2). The entire solution must include source code, design descriptions, and demonstrate functionality via script files, culminating in packaging all components into a tar.gz archive for submission.

Sample Paper For Above instruction

The task of calculating updated salaries is fundamental in payroll management systems. Effective implementation requires designing a program that interacts with users for personalized data entry and processes bulk data from files. The overall process involves input collection, calculation, formatting, and file handling.

Design Steps for the Program

  1. Prompt the user to enter their full name, employment status, current salary, and pay increase percentage.
  2. Validate the inputs to ensure they are in the expected formats (e.g., salary and percentage as numeric values, employment status as 'y' or 'n').
  3. Compute the updated salary by adding the percentage increase to the current salary. This involves converting the percentage to a decimal and multiplying it with the current salary.
  4. Format the calculated salary to two decimal places to ensure currency consistency.
  5. Display the result with the user's full name and the updated salary in a readable format.
  6. For the second part, read each line from the input.txt file, splitting the line into last name, first name, current salary, and pay increase percentage.
  7. Calculate the updated salary for each employee similarly by applying the percentage increase.
  8. Write each employee's first name, last name, and the updated salary formatted to two decimal places into the output.txt file.
  9. Ensure the entire process is encapsulated within a Python script, and also create script files for testing purposes.

Implementation of the Program (Source Codes)

The source code for the first program involves collecting user input, performing calculations, and outputting the result. It employs basic input functions, arithmetic operations, and string formatting in Python. The second program reads from and writes to files, handling multiple employees in a loop, performing similar calculations, and saving the data accordingly.

Demonstration of Functionality with Sample Input

Testing the program with the specified input: Name = John Doe, employment = y, current salary = 35042.55, percent increase = 2.1. The program computes the new salary as follows: 35042.55 + (35042.55 * 0.021) = 35879.88, rounded to two decimal places. The output should reflect this calculation accurately.

Conclusions

This approach to salary updating ensures accuracy and usability, supporting both manual entry and bulk processing of employee data. Proper formatting and validation are essential for reliable payroll computation. Packaging all related files creates a comprehensive submission that demonstrates understanding and implementation of file handling, user interaction, and data processing in Python.
