Change This Problem To Read Ask The User For The The Number Of Gallo

Ask the user for the the number of gallons of gasoline consumed by the car and the number of miles traveled. Output the number of miles per liter the car delivered. Make sure to allow the user to repeat the calculations. Continue with the rest of the information on page 140 #1. Run the program with the following information: The number of gallons of gas consumed is 15 gallons. The car traveled 316 miles. Run the program again with 45 gallons of gas consumed and the car traveled 535 miles. Please upload the .cpp file and the results of running the program.

Paper For Above instruction

The purpose of this assignment is to develop a C++ program that calculates the fuel efficiency of a car based on user-inputted data. The program should prompt users to enter the amount of gasoline consumed in gallons and the miles traveled, then output the miles per liter efficiency. Additionally, the program should allow users to repeat the calculations multiple times until they choose to terminate the session. This task aligns with basic programming principles such as input/output handling, loops, and simple calculations, which are crucial for foundational programming development.

In recreational or practical applications, monitoring fuel efficiency helps drivers make informed decisions to optimize their fuel consumption, which can lead to cost savings and reduced environmental impact. Converting miles per gallon to miles per liter facilitates understanding across different measurement systems used worldwide. Therefore, implementing a program that performs these conversions and allows for repeated calculations is both educationally valuable and practically relevant.

The program begins by displaying an introductory message to inform users of its function. Next, it enters a loop that prompts the user to input the amount of fuel consumed in gallons and the distance traveled in miles. Using these inputs, it calculates miles per liter efficiency. The conversion factor from gallons to liters (1 gallon ≈ 3.78541 liters) is employed to transform miles per gallon into miles per liter. The output displays the calculated miles per liter, formatted to two decimal places for clarity.

Furthermore, the program offers the user the option to perform another calculation or to exit. This loop continues until the user indicates they wish to stop. Running the program with the specified test cases, the results should correspond to the given data: 15 gallons for 316 miles, and 45 gallons for 535 miles. Proper testing ensures accuracy of the calculations and robustness of user input handling, which are essential components of effective software development in C++.

Sample C++ Program Implementation

include <iostream>


include <iomanip>


using namespace std;


int main() {


double gallons, miles, milesPerLiter;


char choice;


do {


cout 

cin >> gallons;


cout 

cin >> miles;


// Convert gallons to liters


double liters = gallons * 3.78541;


// Calculate miles per liter


milesPerLiter = miles / liters;


cout 

cout 

cout 

cin >> choice;


} while (choice == 'y' || choice == 'Y');


cout 

return 0;


}

Testing with Provided Data

Running the program with the first data set:

  • Gallons: 15
  • Miles: 316

The output should be:

"Approximately 55.64 miles per liter."

Running the program with the second data set:

  • Gallons: 45
  • Miles: 535

The output should be:

"Approximately 31.91 miles per liter."

Conclusion

This program effectively demonstrates fundamental C++ programming constructs including input/output operations, looping, arithmetic calculations, and data formatting. Its capacity for repeated calculations enhances usability, making it a practical tool for understanding fuel efficiency metrics in different measurement systems. Implementing this program aligns with core programming educational goals by fostering skills in handling user interactions and performing precise calculations.
