Question

PROGRAM LANGUAGE IN C NOT C# or C++

KEEP IT SIMPLE EVEN IF IT IS REDUNDANT PLEASE.

Problem: Driving

Function driving():

Write a function driving(), that updates the odometer and fuel gauge of a car. The function will take in a reference to the variables storing the odometer and fuel gauge readings, along with a double representing the miles per gallon (mpg) the car gets and the number of miles the driver intends to go. The function should update the odometer and fuel gauge readings, accordingly. If the number of miles is greater than the user can go with the fuel he has left, then simply have the car drive until empty and update the odometer accordingly. The prototype for the function is below:

void driving(double* odomPtr, double* fuelPtr, double mpg, double distance);

Note that, you are not allowed to change the prototype of the function.

The return type of the function has to be void.

Also, there should not be any printf() in the the driving function.

main function:

In the main function, at first take the odometer reading, fuel gauge reading, and miles per gallon (mpg) as input.

Then keep taking distance to drive as input until the fuel gauge indicates 0 fuel. After taking the distance to drive, call the driving function with the proper parameters to get update about odometer and fuel and display the update. Display them up to two decimal places.

At the end display the message "No more fuel!"

Sample Input/Output 1:

Enter odometer reading, fuel gauge reading and mpg: 8000 13.5 25

Enter the distance you want to drive: 200

Current reading Odometer = 8200.00, fuel = 5.50

Enter the distance you want to drive: 100

Current reading Odometer = 8300.00, fuel = 1.50

Enter the distance you want to drive: 500

Current reading Odometer = 8337.50, fuel = 0.00

No more fuel!

Sample Input/output 2:

Enter odometer reading, fuel gauge reading and mpg: 90000 2.5 13.5

Enter the distance you want to drive: 500

Current reading Odometer = 90033.75, fuel = 0.00

No more fuel!

Rubric: 3 points

Writing the function with the specification: 1.5 points [changing the specification will result in 0]

Writing the main function with the specification: 1.5 points

Penalty:

Not passing each test case: -0.75 (total -1.5 for 2 test cases)

Bad indented code: -0.75

Answer 1

Code:-

#include <stdio.h>
void driving(double* odomPtr, double* fuelPtr, double mpg, double distance)
{
   if(distance < *fuelPtr*mpg)
   {
       *odomPtr += distance;
       *fuelPtr -= (distance/mpg);
   }
   else
   {
       *odomPtr += mpg * *fuelPtr;
       *fuelPtr = 0;
   }
}
int main()
{
   double odomPtr, fuelPtr, mpg, distance;
   printf("Enter odometer reading, fuel gauge reading and mpg: ");
   scanf("%lf %lf %lf", &odomPtr, &fuelPtr, &mpg);
   while(fuelPtr != 0)
   {
       printf("Enter the distance you want to drive: ");
       scanf("%lf", &distance);
       driving(&odomPtr, &fuelPtr, mpg, distance);
       printf("Current reading Odometer = %.2lf, fuel = %.2lf\n", odomPtr, fuelPtr);
   }
   printf("\nNo more fuel!\n");
   return 0;
}
