Write A Program That Uses A Loop To Ask The User To Input

Write A Program That Will Use A Loop Toask The User To Input 3 Studen

Develop a comprehensive program that utilizes iterative control structures to facilitate data collection for multiple students, specifically capturing each student's first name and five associated scores. The program should implement dedicated functions to process this data effectively: one function should handle the input and calculation of the ceiling of the average score for each student, while another should determine the qualitative letter grade based on the average using structured conditional statements. Following the data input for each student, the program must output the student's details—name, individual scores, total scores, ceiling of the average, and the assigned letter grade—to a sequential file. After processing all three students and storing their information, a separate function should read this file and display the stored data on the screen in a clear and organized manner, matching the specified format. The expected output on the screen after data entry should resemble the example: "Mike A", "Sam A", "Frank B". This project emphasizes the integration of loops, functions, file I/O, and conditional logic within a cohesive program structure.

Paper For Above instruction

In this paper, we discuss the development of a structured program that employs loops, functions, file operations, and conditional logic to manage student data input, processing, and display. The goal is to create a user-friendly application that efficiently handles multiple students and provides comprehensive output both to a file and on the screen.

Initially, the program prompts the user to input data for three students using a loop. For each student, the first name is captured, followed by five scores. To maintain modularity and clarity, the program defines a function dedicated to entering five grades for a student. This function ensures accurate data entry and calculates the average score. Subsequently, another function computes the ceiling of this average, ensuring that fractional parts are appropriately rounded up to the next integer, which provides a conservative estimate of the student's performance.

The program also includes a function to determine the letter grade corresponding to the student's average score. Using if...else if conditional statements, the function assigns grades such as A, B, C, D, or F based on predefined score ranges. This approach models real-world grading policies, providing a qualitative assessment of student performance.

Once the data for each student (name, scores, total, ceiling average, and grade) is processed, it is written to a sequential text file. This file acts as a persistent storage medium, capturing all relevant information in a format suitable for later retrieval. After all student data has been recorded, a separate function reads from this file and displays the stored information on the screen. The output is formatted to clearly show each student's name, scores, total, ceiling average, and grade, facilitating easy interpretation and comparison.

This program demonstrates the effective integration of control structures, such as loops and conditionals, with functions for modular programming. The use of file operations for data persistence underscores practical skills in handling data storage and retrieval. Overall, the project provides a comprehensive example of how to manage multiple data inputs, process and store results, and present information in a clear, organized fashion.

Implementation

The implementation is divided into several key components:

1. Data Input Loop

A for loop iterates three times, each representing a student. During each iteration, the program prompts for the student's name and calls functions to input five scores, compute the average and its ceiling, and determine the letter grade.

2. Functions Developed

• Input Scores Function: Accepts five scores from the user, calculates their sum, computes the average, and returns the total and average.
• Ceiling Function: Calculates and returns the smallest integer greater than or equal to the average score.
• Grade Determination Function: Uses if...else if statements to map the numeric average to a letter grade.

3. File Operations

After processing each student, data is formatted and written into a file. Once all students are processed, the program reads back the data and displays it on the console for verification and presentation.

4. Output Formatting

The output displays each student's name, five scores, total score, ceiling of their average, and corresponding letter grade. Such formatting enhances readability and makes it easier to evaluate student performance at a glance.

Conclusion

This program exemplifies fundamental programming concepts such as looping, modular function design, file I/O, and conditional logic. The design promotes code readability, reusability, and efficiency, aligning with best practices for software development in educational contexts and beyond.
