Taking string input in user defined object array

Question

I was trying to input 'make' of the car, which can be a multi-word string (eg. Hudson Hornet). But my code is just skipping the getline(cin, arr[i].make), i.e. it is not allowing me to enter the make value. But when I used 2 getline(cin, arr[i].make) one after the other, then it is letting me input the value of make.

I am not able to understand what is the reason for this, as I have studied that getline() is appropriate to input multi-word strings?

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

struct car
{
    string make;
    int year;
};

int main(){
    int n;
    cout<<"How many cars do you wish to catalog? ";
    cin>>n;
    car *arr = new car[n];
    for(int i=0; i<n; i++){
        cout<<"Car#"<<i+1<<endl;
        cout<<"Please enter the make: ";
        getline(cin, arr[i].make);
        cout<<"Please enter the year made: ";
        cin>>arr[i].year;
    }
    cout<<"Here is your collection:\n";
    for(int i=0; i<n; i++){
        cout<<arr[i].year<<" "<<arr[i].make<<"\n";
    }
    return 0;
}
