Exception Handling C++

Hey guys I am trying to do some work with exception handling and I had to create and array with 100 elements in the main to hold cars in inventory, and create and int numCars to hold number of created cars. Then I had to create a for loop that iterates 10 times and each time it should.

1) Prompt user for make and store in a string
2) Prompt user for a model and store it in a string
3) Prompt user for a color and store it in a string
4) Prompt user for a year and store it in a int
5) Prompt user for a mileage and store it in a int
6) Prompt user for a price and store it in a int
7) Create a new car with the 1-6 variables
8) Add 1 to numCars and store the new car in the array using NumCars as the subscript. Then I need to use a loop to print all of the information. While making sure to loop from 1>numCars so it only prints out cars there.


Can someone please help me with step 8 thats all that I am lacking to having my program complete! Then once that is done I asked the teacher for a few extra things to try to that I can further my knowledge. He sent me a second part to the program that is not for a grade just extra practice. But I have to figure out how to get num 8 before I can practice other stuff. Here is my code so far!

Hey guys I have one more question! I am trying to throw some exception handling in and I am having a problem. When an exception occurs the program is still wanting to run...is this normal?? Because I would like for it to say..."Invalid Year entered, please restart program" And it stop there!

Here is my code

Code:

#include "CarClass.h"
#include <vector>  // this allows user to create a vector
using namespace std;

    
int YearsInvalid(int tempInt)
    {
        if (tempInt < 1990)
            throw "Error:  Invalid Year Entered.\n";
        else
            return tempInt;
    }

int main() {

    
        Car Car[100]; // sets amount of cars
        int numCars;
        string tempString;
        int tempInt;

        {
            //Loop that adds cars to array
            for ( numCars=0 ; numCars < 10 ; numCars++ )
            {
                cout << "Enter the Make of the Car: ";
                cin >> tempString;
                Car[numCars].setMake(tempString);

                cout << "Enter the Model of the Car: ";
                cin >> tempString;
                Car[numCars].setModel(tempString);

                cout << "Enter the Color of the Car: ";
                cin >> tempString;
                Car[numCars].setColor(tempString);

                cout << "Enter the Year of the Car: ";
                cin >> tempInt;
                Car[numCars].setYear(tempInt);
                
                //Try Catch

                    try
                        {
                            YearsInvalid(tempInt);
                        }
                    catch (char *exceptionString)
                        {
                            cout << exceptionString;
                        }
                    cout << "End of program!!\n";


                cout << "Enter the Mileage of the Car: ";
                cin >> tempInt;
                Car[numCars].setMileage(tempInt);

                cout << "Enter the Price of the Car: ";
                cin >> tempInt;
                Car[numCars].setPrice(tempInt);

                cout << "__________________________________________________________\n"<< endl;

            }
        }

            for(int i=0 ; i <=numCars; i++)
        {
            Car[i].car_details();
        }

        return 0;
    }

I have attached my output!!!

When my code is done I should be able to do this! Test the program and give it 5 valid cars and 5 cars with invalid values. And the loop at the end should print the valid Cars! So I guess I do not need it to start over..but just continue and only store the cars with valid values!
