C++ read the content from two lines of document and store in two variables

I am trying to open a ".txt" file and read the content from the first line and the content from the second line. There are some numbers separated with a simple "space" on both lines of the ".txt" file.

How can I read the content from the first line and save each number in x[100] and read the content from second line and save each number in y[100]?

PS: I am a beginner.

#include<iostream>
#include<fstream>
using namespace std;
int main() {
    int x[100], y[100], i=0;

    ifstream myfile("something.txt");

    while(myfile >> x[i]) {
        cout << x[i] << "\n";
        i++;
    }
    return 0;
}

Thank you so much!
