Below is my code for a class car efficiency program but I have some errors with the get_gas function. if you can help would appreciate it.
#include <iostream>
#include <cmath>
#include <cstdlib>
using namespace std;
class Car
{
public:
Car();
Car(double);
~Car();
void add_gas(double);
double get_gas(double);
void drive(double);
private:
double fuel_level;
double fuel_eff;
double distance;
double add;
};
Car::Car()
{
}
Car::Car(double z)
Car::Car(double z)
{
fuel_level = 0;
fuel_eff = 0;
distance = 0;
add = 0;
fuel_eff = z;
}
void Car::add_gas( double x)
{
add = x;
}
void Car::drive( double y)
{
distance = y;
}
double Car::get_gas(double a)
{
a = fuel_eff * add;
fuel_level = (a * distance)/fuel_eff;
return fuel_level;
}
int main()
{
cout << " \n *** Car Class Testing Program *** \n " << endl;
cout << " Enter fuel efficiency in miles / per gallon: ";
double fe;
cin >> fe;
cout << " How many gallon do you want to fill in the tank?: ";
double gas;
cin >> gas;
cout << " How many miles do you want to drive?: ";
double miles;
cin >> miles;
Car my_beemer(fe);
my_beemer.add_gas(gas);
my_beemer.drive(miles);
cout << " You will have ";
cout << my_beemer.get_gas();
cout << " gallons left in the tank after drive. " << endl;
return 0;<< moderator edit: added code tags: [code][/code] >>
