Write a function that calculates the annual cost of commuting to work for an arr

Question

Write a function that calculates the annual cost of commuting to work for an array of five distances. The function should take as arguments an array that contains the distances, the miles per gallon of the vehicle, and the number of days a year that the commute is made. Assume gas is $3.00 a gallon. Print the annual cost of the gas for each distance calculation.

Use the formula:

annualCost = ((distance / mpg) * cost per gallon) * days commuting

Use the header:

void calculateCost(int distanceArray[], float mpg, int daysPerYear);

For example:

int distancesArray[5]={150,60,120,90,270};

float mpg=30.0;

int daysPerYear =15;

Would print out:

$225

$90

$180

$135

$405

in C++

Explanation / Answer

#include<iostream>

#include<fstream>

using namespace std;

void calculateCost(int distanceArray[], float mpg, int daysPerYear)

{

double cost;

for(int i=0;i<5;i++)

{

cost = (distanceArray[i]/mpg)*3*daysPerYear;

cout << "$" << cost << endl;

}

}

int main()

{

int distancesArray[5]={150,60,120,90,270};

float mpg=30.0;

int daysPerYear =15;

calculateCost(distancesArray,mpg,daysPerYear);

return 0;

}
