How can i make this program accept a users input for the make, yearmodel.
You can cin to temp variables in main then pass those to the car constructor:
1
2
3
4
5
6
|
cout << "Enter the make: ";
cin >> tempMake;
// do same for tempYearmodel
Car test(tempYearModel, tempMake, 0);
|
This will create a car object with the user inputted yearmodel and make, and 0 speed.
This is my updated code, i changed it around a little.

My errors are line 76 and 77, i cant get them to register the input for year, make and speed.

However, if i can only do it by making a temp where would i define the temp variables and put them.
Change the header of getDisplay to:
As it is now the function isn't related to Car, so it does not know those values.
Ok heres my updated code

Now i get one error say getDisplay prototype not defined. Line 125
You need to create a Car object and call it using that.
You mean something like Car display;
when i try to make a object it tells me no default constructor, even if i do
Car car;
Yeah, because you never defined a default constructor. You can change your constructor to:
1
2
3
4
5

Car::Car(int Yr = 0, string Mk = " ", int Spd = 0)
{
Year = Yr;
Make = Mk;
Speed = Spd;
