Introduction

Arrays are fundamental data structures in programming that store collections of items, enabling efficient processing and manipulation. A common and highly useful task involves managing an array of numerical data, such as grades, temperatures, or sales figures. For this assignment, I will illustrate a task involving processing an array of test scores to determine the highest score, the lowest score, and the average. This task demonstrates how to populate an array, process its items, and output meaningful results, making it relevant for educational purposes, data analysis, and performance evaluation.

Brief Description of the Task

The goal of the task is to create a program that manages a collection of student test scores stored in an array. The program should populate the array with sample scores, process these scores to find the maximum, minimum, and average scores, and then output these results. This process helps in evaluating student performance and providing insights into overall class results.

Array Population

The array will be populated with predefined scores to simulate real input. These scores can represent student grades on an exam, for example, with values ranging from 0 to 100. Populating the array involves assigning specific values to each element, either manually or through a loop if generating programmatically.

Processing the Array

Processing involves iterating through the array to identify:

- The highest score

- The lowest score

- The sum of all scores to calculate the average

This requires a loop to traverse each element and comparisons to update maximum and minimum values. The sum will be accumulated as the loop progresses, and the average will be computed after the loop completes.

Outputting the Results

Results should include:

- The maximum score

- The minimum score

- The average score

These could be displayed through console output or in a user interface within the Visual Logic environment. Displaying the entire array is optional but can be included for completeness.

Pseudocode

BEGIN


DECLARE scores[10]


DECLARE maxScore, minScore, total, average


SET total = 0


-- Populate the array


ASSIGN scores[0] = 78


ASSIGN scores[1] = 85


ASSIGN scores[2] = 92


ASSIGN scores[3] = 69


ASSIGN scores[4] = 74


ASSIGN scores[5] = 88


ASSIGN scores[6] = 90


ASSIGN scores[7] = 67


ASSIGN scores[8] = 81


ASSIGN scores[9] = 77


-- Initialize max and min


SET maxScore = scores[0]


SET minScore = scores[0]


-- Process the array


FOR i FROM 0 TO 9


IF scores[i] > maxScore THEN


SET maxScore = scores[i]


ENDIF


IF scores[i] 

SET minScore = scores[i]


ENDIF


SET total = total + scores[i]


END FOR


-- Calculate average


SET average = total / 10


-- Output results


DISPLAY "Highest score: " + maxScore


DISPLAY "Lowest score: " + minScore


DISPLAY "Average score: " + average


END

Creating the Visual Logic Program

Using Visual Logic software, create a flowchart following this pseudocode:

- Initialize an array with predefined scores.

- Set variables for maxScore, minScore, total, and average.

- Use a loop to traverse the array, updating maxScore and minScore as needed and summing the scores.

- Calculate the average after traversal.

- Display the results.

Ensure each step of the pseudocode is accurately represented in the flowchart, including decision points for maximum and minimum comparisons and calculation steps.

Conclusion

This assignment demonstrates essential programming concepts such as array management, iteration, conditional logic, and output display. By performing these steps, the program provides meaningful insights into data analysis, which is applicable in various real-world scenarios, such as educational assessments and performance reviews.
