Question

c++, use the skeleton code to make a program of the following

include tinclude using namespace std; class car public: //define your functions here, at least 5 private: string name; int mpg; double price int horsepower; // feel free to add more atributes int main() // create you objects, call your functions // define member functions here For this lab, write a program that does the following: Creates a class based on the car skeleton code (you may make modifications) . Creates 5 car objects (you do not need to prompt the user for these, they can be hard coded in) Allows the user to select 3 cars to compare (you may want to store these 3 objects in an array or vector) . Adds at least 5 meaningful member functions, some of which that compare 3 cars to each other. These functions could include: find best gas mileage, find lowest price find greatest horsepower, etc . In main, the program I/O should: .Let the user choose which 3 cars to compare Let the user select which comparison(s) they want to run .

Answer 1

cpp code:

#include <iostream>

using namespace std;

//car class
class car
{

public:
//constructor
car()
{

}
//set the values
void setValues(string n,int m,double pr,int hp,int ca)
{
this->name = n;
this ->mpg=m;
this->price=pr;
this->horsepower = hp;
this->capacity= ca;
}
//return the mileage
int getMileage()
{
return mpg;
}
//return the price
double getPrice()
{
return price;
}
//return the hp
int getHorsepower()
{
return horsepower;
}
//return the capacity of fuel tank
int getCapacity()
{
return capacity;
}
//return the name
string getName()
{
return name;
}
//variables
private:
string name;
int mpg;
double price;
int horsepower;
int capacity;
};
//function declarations
string* compare(car c[]);
int main()
{
car c[5]; //array of objects of car class
  
//set vlaues
c[0].setValues("Datsun",28,4.1,250,35);
c[1].setValues("Renault",22,5.0,350,28);
c[2].setValues("Tiago",30,3.5,220,27);
c[3].setValues("BMW",35,8.0,330,32);
c[4].setValues("Ford",29,7.2,250,30);

string* carName;

carName =compare(c); //call the compare function
  
//print the 1st three names of car
for(int i=0;i<3;i++)
cout<<"\n"<<i+1<<". "<<carName[i];

cout << endl;
return 0;
}
//get the name of best mileage car
string bestMileage(car c[] )
{
int best = 0;
int index;
for(int i=0;i<5;i++)
{
if(best<c[i].getMileage()){
best= c[i].getMileage();
index= i;
}
}
return c[index].getName();
}
//return lowest price car name
string lowestPrice(car c[])
{
double best = 99999;
int index;
for(int i=0;i<5;i++)
{
if(best>c[i].getPrice()){
best= c[i].getPrice();
index= i;
}
}
return c[index].getName();
}

//return greatest hp car name
string greatestHP(car c[])
{
int best =0;
int index;
for(int i=0;i<5;i++)
{
if(best<c[i].getHorsepower()){
best= c[i].getHorsepower();
index= i;
}
}
return c[index].getName();
}

//return greatest capacity car name
string greatestCapacity(car c[])
{
int best =0;
int index;
for(int i=0;i<5;i++)
{
if(best<c[i].getCapacity()){
best= c[i].getCapacity();
index= i;
}
}
return c[index].getName();
}

//compare the cars and get three best car
string* compare(car c[])
{
string* carObject= new string[3];;

carObject[0]= bestMileage(c);
carObject[1]= greatestHP(c);
carObject[2]= greatestCapacity(c);

if(carObject[0]==carObject[1])
carObject[1]= lowestPrice(c);
if(carObject[1]==carObject[2])
carObject[2]= lowestPrice(c);
if(carObject[0]==carObject[2])
carObject[2]= lowestPrice(c);

return carObject;

}

output;
