#include <iostream>
#include <string>

struct Car{
    std::string model;
    unsigned int year;
};

int main(){
    using namespace std;

    int carNum;
    cout << "How many cars do you wish you catalog? ";
    cin >> carNum;
    Car * cars = new Car[carNum];

    for (int i=0;i<carNum;i++){
        cout << "Car #" << i << endl;
        cout << "Please enter the make: ";
        getline(cin, cars[i].model);

        cout << "Please enter the year made: ";
        cars[i].year = cin.get();
    }

    cout << "Here's your collection" << endl;

    for (int i=0;i<carNum;i++){
        cout << cars[i].model << " " << cars[i].year << endl;
    }

    delete [] cars;

    return 0;
}

Quando executo o programa, ogetline(cin, car[i].model) apenas pule. Por que é isso

como isso

Car #2
Please enter the make: Please enter the year made:
