Fuel Economy, A fuel economy study was carried out for five models of cars. Each car was driven 100 miles, and then the model of the car and the number of gallons sued were placed in a line of the file Mileage.txt Table 7.22 shows the data for the entries of the file. Write a program to mileage. See Fig 7.81 The program should utilize an array of structures with upper bound 4, where each structure has three members.

The first member should record the name of each model of car. The second member should record the number of test vehicles for each model. The third member should record the total number of gallons used by that model.

This paper presents a comprehensive solution to the programming task of analyzing fuel economy data for five different car models using Visual Basic (VB). The primary goal is to utilize an array of structures with three members to organize and process data collected from a mileage test conducted on each model over 100 miles. The structure tracks the number of test vehicles per model, total gallons used, and the model's name, with functions implemented in LINQ queries to compute the necessary aggregates.

Initially, the data from Mileage.txt consists of lines containing the car model's name and gallons used for each test vehicle. The data is parsed into an array, which simplifies subsequent processing. To effectively organize this data, a structure called CarModel is created with three members: ModelName as String, NumVehicles as Integer, and TotalGallons as Double. An array, CarModels, with an upper bound of 4, is used to hold information about the five car models, assuming zero-based indexing or adjusting accordingly.

Two crucial functions, NumCars and NumGals, are implemented using LINQ queries. The NumCars function counts the number of entries in the data array with a given model name, returning an integer. The NumGals function sums the gallons used for all entries matching the specified model, returning a double. These functions facilitate efficient calculation of the number of test vehicles and total gallons per model, which are then used to compute miles per gallon (MPG) and analyze fuel efficiency.

The main processing involves iterating over each unique car model, invoking NumCars and NumGals to fill the structure members accordingly. The MPG for each model is calculated by dividing the total miles driven (100 miles per test) by the total gallons used for that model. The results are displayed in a table format, which can be viewed in a data grid or console output. Additional features include highlighting models with high or low MPG (above 30 or below 20) to provide visual cues for efficiency analysis.

This approach encapsulates best practices in structured programming, LINQ data queries, and user interface interaction. It demonstrates how to manage and analyze vehicle fuel economy data effectively using VB.NET, which is valuable for automotive studies, environmental assessments, and optimization of fleet operations.

Conclusion

By leveraging structures with multiple members, LINQ for data processing, and visual cues for performance anomalies, this program offers a robust framework for fuel economy analysis. The techniques highlighted can be extended to larger datasets, additional metrics, and more sophisticated visualizations, making this approach both scalable and adaptable for various transportation data analytics.
