C++ input a line of unknown number of integers

In the recent written test, the programming question encountered such a required input, and it was necessary to input a line of integers, the number of which was unknown, and then separate the integers with spaces, as shown below:

11 22 333 45 62

The code looks like this:

int main()
{
    vector<int> inputs;
    int n = 0, k=0;
    int i;  
    cin >> i;
    inputs.push_back(i);
    while (cin.get() != '\n')   { 
        cin >> i; 
        inputs.push_back(i);
    }   

    system("pause");
    return 0;
}

A more complete code is shown below. The programming problem is to find the Kth largest number in a given sequence of integers:

#include<iostream>
#include<vector>

using namespace std;
int find_k_max_nums(vector<int> array, int k){
    int res = 0;
    sort(array.begin(), array.end(), greater<int>());
    res = array[k - 1];
    return res;
}

int main()
{
    vector<int> inputs;
    int n = 0, k=0;
    int i;  
    cin >> i;
    inputs.push_back(i);
    while (cin.get() != '\n')   { 
        cin >> i; 
        inputs.push_back(i);
    }   
    cin >> k;

    int res = find_k_max_nums(inputs, k);
    printf("%d\n", res);


    system("pause");
    return 0;
}

The result is as follows:
