Question

The program is to be called CarClub

The application will display menu as below

1. load cars

2. display all cars

3. search car

4 count cars older the 30 years

5 exit

Please enter your option:

Load car menu should read input data from text file name (car.txt)

Car class have 4 data members which are. Car make, car model, car year and car price

In addition

If both car year and price were not provided, year has a default value as 2020 and price has a default value as $20000

If only price was not provided, price should be set to a default value based on this table

2015<year<=2020 and price has a default value as $20000

2010<year<=2015 and price has a default value as $14000

1980<year<=2010 and price has a default value as $7000

2015<year<=2020 and price has a default value as $20000

year<=1980 and price has a default value as $40000

Using dynamic memory allocation to store Car Object

You should implement at least 1 custom excepetion and 1 file exception

You have to implement 1 operator overloading for operator "<<" to use as a print

WHY IS BUILD FAILED?????

Hey, i can see there are some mistakes in the program. It would be difficult for you to understand by mentioning one by one since there is no numbers for the code lines so I'll just type all the code :

include <iostream>
using namespace std;
#include<string>

#ifndef _CAR_
#define _CAR_

class Ccar
{
private:
string make;
string model;
int year;
double price;


public:

Ccar(string="", string="", int=2020, double=20000);
~Ccar();

// setters
void setMake(string);
void setModel(string);
void setYear(int);
void setPrice(double);

// getters
string getMake();
string getModel();
int getYear();
double getPrice();

friend ostream& operator<<(ostream& out, Ccar& param);
};

#endif

#include "Ccar.h"

void Ccar:: setMake(string){
make=make;
}
void Ccar :: setModel(string){
model=model;
  
}

void Ccar :: setYear(int y){
y=year;
  
}

void Ccar :: setPrice(double p){
p=price;
}

// getters

string Ccar::getMake()
{
return make;
}
string Ccar::getModel()
{
return model;
}

int Ccar::getYear()
{
return year;
}
double Ccar::getPrice()
{
return price;
}

#include <exception>
using namespace std;
class myexception: public exception{
// exception implementation???
};

#include <fstream>
#include "Ccar.h"

int main() {
int option, i, numberOffCars, year = 0;

}
  
break;
  
case 4: // count the cars older than 30 years

break;

} catch (exception& ex){
cout << ex.what() << endl;
}
}
while (option !=5); // 5 exit option
delete[] carList;
}
catch (bad_alloc&)

}

Hey, hope this helps u,if so give a thumbs up, it means a lot thanks:) In case of any problem, write a comment I'll sure be helping you. Have a good day:)
