Creating a Class

[TheIncredibleZ1]

I have been learning C++ fairly well for the past few months in a course I'm taking, but I'm having a fair amount of difficulty creating a class. I have my first few accessor functions defined in a header, but I think that the trouble lies in the definition of the constructor I have.

Car::Car(int NewYearModel, string newMake)
{
     yearModel = newYearModel;
     newMake = make;
}

In my function main(), I have an instance of my car class, auto, with arguments passed through. Yet, I recieve the error of a missing semicolon when, in fact, all lines before it have semicolons.

I have tried my book, a friend, and numerous web resources and nothing seems to make sense. Any assistance would be greatly appreciated.

I think line 4 should be make = newMake;

I get some new errors with that change. Each of my "new" variables are coming out as undeclared. I can show what's there even with that new edit. I also get an "expected ; before } token" error at line 14, but all preceding lines have their proper semicolons.

#include "Car.h"

Car::Car()
{
     int newYearModel = 0;
     int newSpeed = 0;
     string newMake = "";
}

Car::Car(int NewYearModel, string newMake)
{
     yearModel = newYearModel;
     make = newMake
}

Car::~Car()
{
           
}

int Car::getYearModel() const
{
     return newYearModel;
}

string Car::getMake() const
{
     return newMake;
}

int Car::getSpeed()
{
     return newSpeed;
}

You are missing a ; at the end of line 13

Fixed it. I'm now working on my function, and using another webpage as a guide.

int main()
{
    Car auto; //instance of class Car
    int autoYear; //year of auto
    string autoMake; //make of auto
    int autoSpeed; //speed of auto
    
    cout << "Enter the year model of your car. ";
    cin >> autoYear;
    cout << "Enter the make of your car. ";
    cin >> autoMake;
    
    auto.setYear(autoYear); //stores input year
    auto.setMake(autoMake); //stores input make
    
}
    

It now says my declaration Car auto; does not declare anything. I'm also getting a bunch of "expected primary-expression before 'auto' " as well as semicolon errors.

[tom221b]

Use something other than auto. this word is reserved or something(not sure about this). Make sure that you include "car.h" and all other required headers. You need a return statement too.

You are correct. auto is a reserved C++ keyword.

What's going on your default constructor?

Car::Car()
{
     int newYearModel = 0;
     int newSpeed = 0;
     string newMake = "";
}

You're declaring and initialising three local variables and then... doing nothing with them.

EDIT:

And then in your other constructor:

Car::Car(int NewYearModel, string newMake)
{
     yearModel = newYearModel;
     make = newMake
}

you're ignoring your first argument entirely.

Presumably yearModel, newYearModel and make are all class members, for this to compile? You haven't shown us your class definition, so I can't be sure.
